Manchester United manager Sir Alex Ferguson celebrated the performances of Robin van Persie and Javier Hernandez during his side’s 4-0 Premier League win against Wigan.

Both the Dutchman and the Mexican scored twice as the Red Devils maintained their seven point advantage at the top of the table.

Manchester City boss Roberto Mancini singled out Robin van Persie as the key man in this term’s title race recently, praise that was echoed by Fergie after the game:

"We knew we were getting a top player who would make a difference to the team. That is why we went for him.” He told Sky Sports.

"Robin is a completely rounded footballer. He has great international experience, he's played for Arsenal for seven years and he came to us at the very peak of his career.

"His ability to make and take goals is fantastic. His play for his first goal was absolutely magnificent, his turn, his balance, no drawback, just side footed it in. It was a really good goal."

Although Hernandez has not stolen the headlines in quite the same fashion as RVP this season, his brace took his tally to 12, drawing applause from his manager:

"Since Javier came, he has shown he is a penalty-box player,

"He is tremendous. He latches onto things. He is brilliant."

The Scot went on to say that a number of key players will be rested for this weekend’s FA Cup clash with West Ham:

"We will make a few changes for the cup tie,

"We took Michael Carrick off as soon as we got the third goal. They deserve a break and they have played in all the games.

"We'll have a look at the situation. We've got plenty of players to freshen it up."
