Manchester United legend Paul Scholes has spoken of the early problems of Nemanja Vidic and Patrice Evra.
Recent United signings have been criticised for failing to live up to their billing, in particular Paul Pogba.
But Scholes says: "I remember Patrice Evra and Nemanja Vidic had really difficult starts in their first six months but what players they turned out to be.
"Some players learn quicker than others.
"A few of these players are learning a bit slower than they should be."
