Former Manchester United player Louis Saha believes that manager David Moyes could struggle to clinch his top transfer targets this summer.
The North-West outfit are unlikely to provide Champions League football next season due to being 10 points adrift of fourth place with five games left to play.
"It is a huge blow," Saha told talkSPORT. "People were not expecting something like this to happen. It is now about making sure the transfer market is well worked.
"We all know money is very important in terms of finding the right players and when you don't appear in the Champions League, it is a big blow."
Bayern Munich midfielder Toni Kroos and Borussia Dortmund's Marco Reus are among the players that have been linked to Old Trafford.
