Manchester United manager Jose Mourinho has insisted that he won't do 'anything crazy' in the transfer market this summer in an attempt to catch Manchester City.

City were crowned Premier League champions on Sunday after United's shock loss at home to West Brom, but it has been inevitable for some time that Pep Guardiola's side would win the title.

Mourinho has spent more than £300million since he was appointed as United manager in 2016 but he is adamant that he won't go overboard in terms of bringing in new players this summer.

Jose Mourinho insists that Manchester United won't 'do anything crazy' in the transfer market

'We are not going to spend more than we can. We are not going to do anything crazy,' Mourinho said, as reported by Sky Sports. 'We are just trying to improve a little bit more. That's what we are going to try.

'Everybody will try to improve - like we did from last season. Last season we finished sixth and this season we are going to finish, hopefully, second.

'Next season, we are going to try to improve, but let's see what happens. Maybe also City will invest massively and they don't let the others close the gap to them, I don't know.

Mourinho is determined to regain the title from Pep Guardiola's City side next season

'But it is not about us and them, it is about us and them and Liverpool and Arsenal and Chelsea and Spurs. It is not City and United. It is about the six.'

The likes of Paul Pogba and Romelu Lukaku have arrived at United during Mourinho's tenure but the title has still proven to be beyond the Red Devils.

City, given their financial firepower, are likely to make further significant additions to their squad this summer.

United still haven't won the title since the retirement of Sir Alex Ferguson in 2013.

Despite missing out on winning the league, United still have an opportunity to end the season with some silverware as they are through to the semi-finals of the FA Cup, where they will face Tottenham.
