Jamie Redknapp insists Ole Gunnar Solskjaer must address Manchester United’s recent “record of making good players turn into bad ones”.
United eventually sealed the £68m deal for Bruno Fernandes from Sporting this week, and the midfielder could make his debut against Wolves on Saturday.
But if he is to prove a long-term success, Solskjaer and must provide a better platform for him, says Redknapp.
“He’s a very, very talented player,” Redknapp told the Sky Sports Football Weekend Preview podcast.
“I saw him last summer in the Nations League and I was very impressed with him. He got 20-odd goals from midfield last season and he’s got an unbelievable strike from distance. If you look at his numbers they’re amazing.
“Frank Lampard is the best I’ve ever seen for scoring goals from midfield but this guy is doing it as well.
“But what you have to remember is, right now United have an amazing record of making good players turn into bad ones.
“They’ve got to look after this guy because he’s a super player. But the players they’re signing have got to perform better and they have to find a way of getting the best out of these players.
“I don’t subscribe to this theory they keep signing bad players, they’re just not working correctly with these players and they need to create an environment where these players know if they’re not doing well enough and not just be able to turn it on when they want.
“And that sometimes comes down to the manager.”
