Cape Town - Manchester United midfielder Marouane Fellaini concedes competition for places is intense, but admits that is to be expected at a club of their stature.
Rumours began to circulate that Fellaini was headed towards the exit door after his former boss David Moyes was appointed by Sunderland, but both player and manager have denied any such a move was on the cards.
The lanky 28-year-old believes he has earned new United manager Jose Mourinho's trust in pre-season and is looking forward to having a good campaign at Old Trafford.
"When you play for United you have to have competition. There are a lot of good players with quality, but I'm confident," Fellaini told MUTV.
"Everyone has to fight for his place; I think that's why you give everything on the pitch. It's not easy, so if you're not good or you don't do well, the other players then take your place and I think they always push you to be the best.
"I think I can help the team, I can contribute, I can do well for this team. I think the manager trusts me - he knows what I can do, he knows my qualities and that is important. I want to give everything for the team."
