Early start for Moyes as new Man United boss arrives at 8am for first day in charge... and here are the challenges facing the Scot

David Moyes has arrived at Manchester United's Carrington training ground to officially begin work as Sir Alex Ferguson's successor.
Moyes drove into the vast complex in a sponsored Chevrolet at just after 8am this morning, stopping briefly to wait for security barriers to be raised before heading into work.
It marks the start of a new era for the Red Devils after Ferguson ended his 26-year tenure in May but Moyes look keen to retain a little of his Everton identity as he arrived with a blue folder on the passenger seat.

Here we go: David Moyes arrives at Carrington for his first official day in charge of Manchester United

In a sign of the changing nature of life at United, within minutes of Moyes' arrival the club were confirming another regional partnership - this time with leading Thai telecommunications company True Corporation Plc.

As True will be an associate match sponsor for United's opening tour match against Singha All Stars in Bangkok on July 13 - Moyes' first in charge - it will be part of a significant day in Red Devils' history.

Before that, Moyes has a few issues to deal with and here, Sportsmail dissects the pressing issues he faces as he takes over at United.

1. Put an end to the Rooney saga

The future of Wayne Rooney will dominate the first week of the David Moyes reign as Manchester United manager. Following his final home match in charge, Sir Alex Ferguson claimed that Wayne Rooney had indicated his wish to leave the club, but Rooney and his representatives remain adamant that the striker was seeking assurances about his future rather than angling for a move.

Decision time: Wayne Rooney's future at Manchester United has yet to be resolved

Moyes is expected to meet with the England man in the next 48 hours and will attempt to persuade Rooney, 27, that his future lies at Old Trafford. Both parties approach the talks with optimism and with the hope of bringing a swift end to the saga. A resolution may be helped by Moyes’ arrival. Rooney’s concerns were believed to have been with his role under the Ferguson regime – particularly the retired manager’s barbs at Rooney’s fitness and the tendency Ferguson had of playing Rooney out of position - rather than a distinct unhappiness with life at United.
The situation, however, could be complicated by the length of Rooney’s current United contract. With his £250,000-a-week deal set to expire in two years time, this is a decisive summer.  If either the club or the player remain unsure about Rooney’s Old Trafford future, United would need to sell this summer in order to recoup the £27 million that they shelled out on an 18-year-old Rooney in 2004.
Should the differences be resolved – which may require a statement from the club accepting that Rooney did not express a clear desire to leave – United would need to offer the forward a new contract that ties him to the club into his early thirties.

Unhappy: Rooney struggled to hold down a starting place at United last season

But with Robin van Persie now the main man, added to the expected development of Danny Welbeck, Shinji Kagawa and Javier Hernandez, do Rooney’s performances justify the honour of being the highest-paid player at Manchester United?
And, if not, would Rooney accept a wage cut?

2. Strengthen the midfield

Manchester United may have strolled to the Premier League title last season but many observers believe that United do not keep the ball well enough and their failure to control football matches has been exploited in Europe during the last two seasons.
The outstanding Michael Carrick aside, United lack quality, consistency and energy in the central midfield position. With Paul Scholes now retired, the onus falls upon Tom Cleverley and Anderson to provide a creative spark but both have been dogged by injury problems and a failure to regularly produce top-drawer performances. A cloud of uncertainty remains over Darren Fletcher’s illness, while Phil Jones long-term future is expected to be at centre-half rather than in midfield.

Barcelona’s Thiago Alcantara is the top target as United seek a new source of invention and goals – United’s highest-scoring midfielder last season was Ryan Giggs with just five goals and two of which were penalties. It has now been eight seasons since a United central midfield player has broken the 10 goal barrier – long gone are the days when United could rely on Scholes to provide fifteen goals from midfield.
Moyes will also be aware that Manchester City and Chelsea have at times overpowered United in recent seasons, and the addition of a dynamic and dominant midfielder would also be welcome - Newcastle's Yohan Cabaye and PSV's Kevin Strootman have been mentioned.

3. Who could be leaving?

Apart from Wayne Rooney, there may be some other players fearing for their Old Trafford future as new manager David Moyes looks to assert his authority. Nani - who is being monitored by Monaco and Juventus - and Anderson were signed as promising youngsters in 2007 but their development has stalled and if anything, the players have regressed in the last eighteen months.
In defence, Patrice Evra, now 32, may feel that the time is right to take one final pay-day at Monaco or PSG should United’s move for Leighton Baines materialise.

The Frenchman is United’s vice-captain and is unlikely to want to play second fiddle to the Everton full-back. Antonio Valencia and Ashley Young both suffered disappointing campaigns last time out but there is a little indication that Moyes intends to allow either winger to move on just yet.

4. Moyes' Boys

With the leading members of Sir Alex Ferguson’s backroom staff having now left the club, all eyes now turn to who David Moyes will bring in.
It is expected that there will be a raft of coaches brought in from Everton, with Steve Round replacing Mike Phelan as assistant manager, Chris Woods replacing Eric Steele as goalkeeping coach and Jimmy Lumsden filling the post of first-team coach after Rene Meulensteen’s departure was confirmed last week.
Former Everton and Manchester United player Phil Neville could also link up with Moyes in a coaching capacity.

It is not expected, however, that Moyes will tinker too much with the running of the
United youth system, with Everton’s academy chief Alan Irvine less likely to make the switch from Merseyside.

5. Dressing room harmony

Much of Ferguson’s success was founded upon the loyalty that he demanded from his players. In the age of player-power, Ferguson proved himself the master man-manager and it will take time for Moyes to command such respect. The players have spoken positively of his appointment but he must not allow the Rooney saga or Evra’s concerns to fester.
Equally, he should use the experience, knowledge and power of senior figures such as Ryan Giggs and Rio Ferdinand. If he keeps the main men on side, Moyes should avoid early divisions emerging.
United go on tour on July 10, providing the perfect opportunity for the new manager to bond with his players and win over those who may be harbouring reservations.
