If Carrick can deliver on expectations, then he could become the first United manager since Ferguson to last more than two full seasons in the dugout. There are plenty of hurdles to clear before that point is reached.
Asked if Carrick can achieve that feat, four-time Premier League title winner Silvestre - speaking in association with Betinia - told GOAL: “Like he said in an interview when he took over, he has to prove himself to the players, to the board that he can be there for longer.
“He can only achieve that if he qualifies always for the Champions League, plays good football and tries to improve the team to win the league. I think he will have time and I think he can do it.
“He's never managed a top club before, but he has so much knowledge about what United is about, about the game. He's been coaching, he's not 38 years old, he's going towards his 50s, he's not a young lad, so he knows himself.
“I hope that his backroom staff is good enough, because it's not a one-man job anymore. You have to manage 25 players with big egos, with big wages. The sporting director has a big role to play as well as the CEO, it's not like before, we can't compare. We can't compare Alex Ferguson, Arsene Wenger and David Dein. Now it's a different ball game, totally different”
