Manchester United manager Jose Mourinho has suggested there are likely to be more ins and outs at Old Trafford before the start of the new Premier League season. The Portuguese coach has already signed three players since taking the reins at United, but Mourinho has suggested his transfer work is far from done this summer.

The Premier League-winning manager recently revealed he would like to sign another player after sealing deals for defender Eric Bailly, midfielder Henrikh Mkhitaryan and striker Zlatan Ibrahimovic, amid rumours of United making a £100m ($129.7m) move for Juventus' Paul Pogba. Mourinho has remain tight-lipped about his specific transfer plans, but he has hinted more players are likely to arrive and leave the club in the coming weeks.

"I understand that [the fans] expect a lot from me but I also expect a lot from them," the 53-year-old said of his relationship with the United supporters, according to ManUtd.com. "There is no chance we will be happy if we are not together and I think the passion [they have] for this club is really amazing.

"It's a new chapter in the club's life. We have brought a few new faces in, we will keep some others but, in the end, it doesn't matter who the manager is, it doesn't who the new players are or who is staying or leaving, it's Man United and Man United is much more than any one of us.

"The passion the fans have is for the club and I feel that I am a club man. I am going to do my best to be happy and to make the people happy."

Mourinho also predicted the Premier League will be more competitive than ever this season, suggesting smaller teams lack fear when facing sides like United. "If you look at the Euros and you see what Wales have done and what Iceland did, I think football is changing," said Mourinho, who has replaced Louis van Gaal as the United manager.

"It's not just about the amazing economic situation that every club in the Premier League has now, which allows them to buy well and buy expensive and good players to compete for the biggest prizes. It's not just about that, it's also about training methods, preparation and mental preparation, and also nobody is afraid of anybody.

"In the past you could smash opponents, if you were one of the best teams, 5-0 or 6-0 and win 10-15 matches in a row. I think these times are over and fewer points will win the title. Even with a handful of defeats you can be champions because the profile of the competition has changed."
