Ole Gunnar Solskjaer will be backed by Manchester United in the transfer window, executive vice-chairman Ed Woodward has promised.
Solskjaer, who made no signings in January, has indicated he wants to oversee a clear-out at Old Trafford.
Ander Herrera and Antonio Valencia are leaving while Juan Mata is out of contract and his future at the club is still unresolved.
United ended the season poorly, with no wins in their final six games in all competitions, losing 2-0 at home to Cardiff City to conclude a Premier League campaign in which they finished sixth.
They will not play in next season’s Champions League, which is likely to deal further damage to any possible transfer budget, but Paul Pogba has been linked with a move away that could bring in a significant sum.
And Woodward has indicated there will be funds for Solskjaer to invest in his squad regardless of player sales, given the club’s continued commercial success.
“The strength of our business means we have the financial resources to continue to provide backing for the manager and creating success on the pitch,” Woodward told investors. “This, as ever, remains our number one goal.
“It [the season] clearly didn’t end the way we hoped, finishing in sixth place and with a disruptive managerial change partway through. However, Ole and the squad battled back from December to be in contention to qualify for the Champions League next season but, ultimately, we came up short.
“While the last few weeks were disappointing, we are delighted to have confirmed the appointment of Ole as our manager on a three-year contract, and to have confirmed key members of the coaching team, Mick Phelan, Michael Carrick, Kieran McKenna and Mark Dempsey will all be remaining at the club.
“Everyone at the club – the board, the manager, the squad and all the staff – are resolute in our desire to get United back to the top of English football. We continually look to improve staff on and off the pitch to achieve this.”
