Manchester United FA Cup winner Mark Robins believes they'll need ten transfer windows to fix the squad.
Coventry boss Robins, who came through the youth ranks at United and won the FA Cup with the club in 1990, has called for patience in manager Ole Gunnar Solskjaer amid the club's worst start to a season for 30 years.
He told talkSPORT: "I'd love to see Ole get the time to be able to build, because he is not doing it in one window; he's going to need six, seven, eight, nine… 10 windows!
"You don't get that time generally. Ultimately what he is doing is trying to implement the processes Sir Alex had in place prior to his retirement.
"I think that is a huge ask. Remember Sir Alex went years prior to winning his first trophy and that will be very, very difficult to replicate because of the modern-day pressures."
