Marcos Rojo has warned Chelsea: Manchester United can still hunt you down.

The Argentine defender has impressed since Old Trafford boss Louis van Gaal paid Sporting Lisbon £16million for him last summer.

Rojo, 24, scored his first United goal in their 3-0 FA Cup replay win over Cambridge United on Tuesday. Set to face West Ham on Sunday, he now believes they can complete an unlikely Double.

"I thought Chelsea were far ahead of us in the table, but everyone at United says we can catch them," the South American said.

"We will not give up hope. We'll first aim to overtake Manchester City, and it is a good challenge for us.

"We have even better chances of winning the FA Cup. I am in good shape, and I'm happy with the way our results are going.

"Louis van Gaal is a coach who gives us a lot of confidence. You can tell he knows a lot about football.

"He always tries to advise us, and if he spots something about your game he'll tell you in private and show you videos about it.

"Angel Di Maria got off to a good start with us. He had a quiet spell, but he's now regaining his best form.

"He is coming to terms with the recent attempted robbery at his house.

"When I scored my goal against Cambridge the fans began chanting: 'Argentina, Argentina.' It makes me very proud for this to happen in England."
