Manchester United goalkeeping legend Edwin van der Sar has warned incoming boss David Moyes he faces a Herculean task to continue Sir Alex Ferguson's winning ways. The 50-year-old Scot will replace his older compatriot as United manager from 1 July, following Ferguson's retirement.

And van der Sar who own four Premier League titles, the Champions League and the FIFA Club World Cup during his time at Old Trafford, feels Moyes will struggle to repeat his former manager's accomplishments. Ferguson leaves United after an incredible 38 trophies in 26 seasons.

"I wish him the best of luck and David Moyes also because it is almost an impossible job to step into. Sir Alex is a great man and a great manager at a fantastic club," the former Dutch international said, adding, "[But] I am sure the manager [Ferguson] and the players and the board are fully behind him. That is all you can ask for."

The present Everton boss, whose Goodison Park contract expires on 30 June, will have several difficult decisions to take when he formally takes charge, including that of Wayne Rooney's future.

The 27­-year-old England international is widely expected to leave Old Trafford in the summer, one way or the other. It is understood Spanish giants Real Madrid will lead the list of clubs interested in his services and president Florentino Perez will bid £25m for the forward.

Other rumoured transfer situations that may require Moyes' consideration is a move for Borussia Dortmund striker Robert Lewandowski, Arsenal defender Thomas Vermaelen and Barcelona midfielder Thiago Alcantra, as well as Inter Milan defender Andrea Ranocchia.

Renegotiated Debts for Manchester United

Meanwhile, in a move that should ease the financial burdens on the club, BBC reports the club's owners have negotiated a new deal to reduce the amount of interest due. United is owned by American business magnate Malcolm Glazer, who leveraged the club against the funds needed for takeover. This has resulted in enormous loan repayments every year. Now however, it is reported that £178m of debt has been refinanced, leading to a speculated £10m a year saving.
