From the look of things 33 years is not too old to remain in a club challenging for next season's title race. Pep Guardiola is not better compared to Ancelotti who knows perfectly why he still kept Modric, extending his contract on a one-year terms even if it is a condition of the club. Manchester City should not start next season without an experienced player in the midfield, departure of De Bruyne creates that vacancy. Pep Guardiola may not see this coming, it will affect his performance.
De Bruyne can perform perfectly if he remains sadly, it's obvious that he won't be staying any longer in the Premier League or any top League.
The weaknesses of a player is best known by the coach. Fans don't notice immediately, but inner industry men do, David Lynch,
in a conversation whether De Bryune would be coming to Liverpool, pointed out that the Belgian is dealing with past glory. Aside his perspective on the City icon, premier league gets very challenging each season and several factors like proficiency determine who leads the table.
