Manchester United's crocked captain Nemanja Vidic has hailed the form of Antonio Valencia.
Vidic feels Valencia has been the key man in their title surge.
"He's done it so many times this season and it seems like he's made a step up and improved.
"I would say he is our best player this season.
"There are one or two others, like Wazza's had a great season and has scored a lot of goals.
"But Antonio has done really well. It's important he's fit and plays all the games because we need him at this time of the season.""He's a great player to play with," he said. "First of all he's a team player who works hard for the team and makes a difference up front.
