Reading midfielder Jem Karacan admits Nani made the difference for Manchester United in Monday's FA Cup clash.

Nani inspired United to a 2-1 win on Monday night.

Karacan told the Reading Post: "It was a tough game and they are a quality side with world-class players. It's just a shame we couldn't take something off them.

"We were doing well, but Nani came on and he has that something different."
