Cape Town - Manchester United midfielder Nemanja Matic insists he didn't feel he had to prove anything to former club Chelsea on Sunday at Old Trafford.
The Red Devils beat the Blues 2-1, thanks to goals from Romelu Lukaku and Jesse Lingard, who helped the hosts fight back from a goal down following Willian's 32nd-minute opener.
Matic started the game in the middle of the park next to Scott McTominay and put in a solid performance against the club where he won four major trophies before signing for United in the off-season.
"I played for Chelsea for three-and-a-half years and I gave my best to win against them and show my quality again," Matic was quoted as saying by ESPN.
"I didn't have anything to prove to them. I wanted to show my new club that I deserve to wear this Manchester United shirt.
"This was a big win and I hope the team will continue like this because every game in this league is a war."
The Serbia international added: "I don't want to speak about why I left Chelsea. I will keep that to myself. I'm happy in Manchester and that's it. Moving to United was good for me. I play for a big club."
United's next match is up against relegation threatened Crystal Palace on Monday, March 5.
Kick-off is at 22:00 (SA time).
