Man. City are targeting four big summer signings despite being able to win all the trophies this season

Premier League champions Manchester City may be on the verge of winning an astonishing treble this season, but that doesn't mean transfer plans are on hold as they look to strengthen even further.

City have already secured the Premier League title – their fifth domestic trophy in six years, all under Guardiola – and now prepare for the FA Cup and Champions League finals against Manchester United and Inter Milan respectively.

But according to The Mirror, City are lining up some big summer targets with Alexis Mac Allister, Julio Enciso, Joshua Kimmich and Josko Guardiol all on their radar.

Brighton midfielder Mac Allister looks most likely to be on the move this summer, with United and Liverpool also interested in the Argentina World Cup winner.

Fellow Brighton player Enciso has burst onto the scene in the second half of this Premier League season and at just 19 years of age, the Paraguayan forward looks to have huge potential.

Bayern Munich star Kimmich is a former pupil of Guardiola and could provide additional versatility in City's defense and midfield should he make the move from Munich.

Meanwhile, Guardiol - who almost joined Chelsea from RB Leipzig in January - is a highly sought-after left-footed centre-back who could also fit seamlessly into City's squad.

None of the players will be free. But it is bad news for City's rivals, who may have thought the Etihad club could go without spending after such unprecedented success in recent years.
