Jose Mourinho has announced how many players Manchester United want to sign in the summer

The winter transfer window closed less than two weeks ago, but stories and rumours about the summer window have already started circulating.

Manchester United have been heavily linked with a world record deal for Antoine Griezmann from Atletico Madrid for €100m. Jose Mourinho wouldn't comment on that rumour, but he did offer some insight into the club's summer transfer plans. "It's not our philosophy independent of the numbers, can you spend £1m, £10m or 100m. It's also the philosophy, the idea and we look at it in this way," Mourinho said in his press conference ahead of United's game against Watford at Old Trafford on Saturday.

"We prefer to bring two, three or four players. Players that feel an idea, a football we try to play, that can improve our squad. We are not interested in signing six or seven or sell six or seven.

"We are not going to play this game, we are stable, so we think our market in the summer will be soft, (it) will be natural. "Some players to leave, some players to come but in a very natural way."

One player who won't be leaving is Zlatan Ibrahimovic. The United manager said he is "totally convinced" Ibrahimovic will remain at Old Trafford for another season. The Swedish striker has scored 20 goals in 38 appearances this season, including 15 in the Premier League, and shows no sign of slowing down, despite being 35-years-old. Mourinho expects him to continue his great form next season, and revealed that Zlatan even refuses to take days off. "He came with the intention to stay two years but in the minds of everyone the first year is going better than every expectation," the United manager said.

"He knows we are going to try again to improve next season and try to share with him in a fantastic way probably the last year of his career at the highest level. "So I'm convinced that he's staying, he’s adapted to the club, to the situation. "I don't see any problem with his family. I give him the possibility of an extra day off to go to Sweden, he doesn’t want this ever, so I'm totally convinced he is going to stay."
