Tottenham boss Mauricio Pochettino says the Premier League's early transfer deadline is a "massive mistake".

The English top-flight are unable to sign players after August 8, while the rest of the big European leagues are free to work the market until September 2.

"I wasn't in agreement [with the early close of the Premier League transfer window] but at that moment they believed that was best for the clubs," Pochettino said.

"But I think he [Levy] and a lot of people now realise it was a massive mistake. I hope that we fix the problem for the next season. I think we need to go back and operate in the same way that they operate in Europe because I think it's massive when you go to compete in the Europa League or Champions League.

"It's so clear that I cannot be happy as a coach that in the last three or four weeks that certain clubs from Europe can unsettle your team.

"For me it's not common sense and we need to go back quick, hope they have a good conversation at the Premier League and go back quickly [to how it was]."
