Manchester City captain Vincent Kompany announced on Sunday that he was leaving the club to move to Anderlecht and Pep Guardiola has already made one player his number one target to take the Belgian's place.
On Saturday Manchester City completed an incredible and history making domestic treble, when they hammered Watford 6-0 in the FA Cup final in Wembley, but just 24 hours later the fans were processing very different news.
Captain, and club legend, Vincent Kompany revealed that he was leaving the club, as his contract was coming to an end, to rejoin former club Anderlecht, where he will become player-manager.
Kompany's influence at City has been unquestionable in turning them into four time title winners and even at 33 he proved how important he is to the team with his late season performances, and goal against Leicester City.
With the former Hamburg player leaving, and Nicolas Otamendi rumoured to follow, City require more depth behind Aymeric Laporte and John Stones and Guardiola has reportedly already set his sights on his number one target.
According to the Daily Mail, Guardiola has made Leicester defender Harry Maguire his top summer priority and he'd likely have to break the club's transfer record to sign the England defender.

Despite the huge amounts spent by City in recent years their transfer record spend is 'just' £60 million, which they spent last summer on then Leicester winger Riyad Mahrez.
Maguire would cost more than that and could even cost more than the £75 million spent by Liverpool on Virgil van Dijk, the current record fee for a defender.
The news could come as a blow to City's local rivals United. The Red Devils wanted to sign Maguire last summer and have once again been linked with him as Ole Gunnar Solskjaer looks to revamp his team.

After the interest from Jose Mourinho last season the Foxes signed the defender up to a new five year deal, after only joining a year earlier.
Leicester aren't keen on selling the defender, who became a national cult hero at last summer's World Cup, but a huge bid could change their mind.
Would Maguire be a good replacement for Kompany?
