Manchester United midfielder Paul Pogba has said there is still a "question mark" over his future following his team's resounding 4-0 victory over Chelsea in the first match of their Premier League campaign on Sunday. The France international said he wanted to leave the club during the close season and was linked with a potential move to Real Madrid or Juventus. Manager Ole Gunnar Solskjaer praised Pogba's professionalism after he set up United's third and fourth goals against Chelsea, but the midfielder said "only time will tell" if he would stay in England. "I always feel good when I play football. I do the things I like, plus it's my job. I give my all every time I go out on the pitch," Pogba told French radio station RMC. "I'm aware that things have been said. Only time will tell. There's always that question mark. "I'm at Manchester. I have fun with my teammates. I always want to win matches and I always give my best when I'm on the pitch." The Premier League transfer window closed on Thursday, a day before the start of the season, but top-flight clubs in England are still allowed to sell players until the European window closes on September 2.
