He probably wouldnt be with us now muller happy gnabry struggled at arsenal
It seems like you're talking about Serge Gnabry, a German professional footballer who plays as a forward for Bayern Munich and the Germany national team.
You're right, Gnabry did struggle during his time at Arsenal, where he played from 2011 to 2016. He made his professional debut for the club in 2012, but failed to establish himself as a regular starter and was eventually loaned out to West Bromwich Albion and Hertha Berlin.
However, after joining Bayern Munich in 2017, Gnabry's career took off. He has since become a key player for the club, scoring over 100 goals and providing numerous assists. He has also been a regular member of the German national team, helping the team win the 2014 FIFA World Cup and the 2017 FIFA Confederations Cup.
It's interesting to note that Gnabry's struggles at Arsenal were likely due to a combination of factors, including his young age, lack of experience, and the competition for places in the team. However, he has since developed into a top-class player and is now considered one of the best wingers in the world.
