David Moyes has around £100million to salvage Manchester United's season, but has been told not to spend it on "quick-fixes".

Chief executive Ed Woodward is willing to bankroll investment in manager Moyes' squad, with the champions struggling to guarantee a top-four finish and Champions league football next season. But the Old Trafford board are adamant they will not panic buy and will only sanction spending if the Scot can land specific targets he has already identified.

And with Moyes admitting he may not buy at all this month, United's proud record of never having finished out of the Premier League's top three is in doubt.

The Reds are understood to have ruled out a January move for Athletic Bilbao midfielder Ander Herrera, whom they tried but failed to sign last summer.

They are also likely to fail in their efforts to land another Spaniard, Atletico Madrid playmaker Koke, whom Moyes has had watched several times.
