Arda Guler is not too worried about Mbappe arrival because they play in different positions so Arda still has the opportunity to get more matches, but usually Arda only plays in non-decisive matches so the challenge is different from the real match. Arda Guler still has 2-3 seasons to improve his career meaning he should be able to take a stand after the next few seasons I mean, a situation like this is certainly not beneficial for him be among the stars so if there is no change and increase in playing time he should move, I mean after the next 2-3 seasons.
Arda Guler nonchalance about Mbappe arrival is understandable given their different positions on field. However Arda limited playing time in non decisive matches is concern. He needs more opportunities to prove himself in high stakes games. With 2-3 seasons left to boost his career Arda must capitalize on his chances and assert himself as starter. If he does not see significant playing time increases it may be wise for him to consider moving to new team where he can truly shine. Staying in backup role among superstar players won't help him grow he needs to take leap and showcase his skills in more meaningful matches.
