Arteta started from scratch, even I felt doubtful when 2 years went on there was no good development with Arsenal. But I was wrong, Arteta was finally able to prove himself and be trusted again. Arteta was then given the trust and facilities to make several transfers. Although in the end they have not been able to become EPL champions. But if you look at the moment Arsenal is very good. I think Arsenal's target this year is to win the EPL.
The thing with Arsenal as a a club is that they don't easily get rid of their managers even after performing poor for long. I witnessed an era where arsenal ended the league in 8th position twice. It was literally a nightmare for the fans. But we've all seen a different arsenal team for the past two seasons now under the same arteta. I think arsenal has the chance of laying their hands on a trophy this season, seeing the quality of player in the team. Odegaard and Merino should be probably out for couple of weeks. Having those two quality in the midfield will help them in competing for major competition. Congrats to arteta and arsenal fans that still trust the process.
IMO, it's not ideal to make comparison of two players that plays in different position for same club, though we can't say the same when it comes to trophies. Kane is a well known striker, and his duty is literally to put the ball at the back of the net which he has been doing for the club. Musiala happens to be a very good midfielder considering his current age, which is clearly an opportunity for him to improve. The both of them contribute to the team, so there is no point comparing them. But assuming the clubs eventually face some kind of financial challenges, and might want to get rid of just one of them, then I think harry is Likely to use the exit. That's just the truth, because Musiala still has lots of years ahead of him, and he is a very good player. Whenever I watch Germany or Munich's game, I always look forward to watching him. He is just my star man in both teams. Regardless, there is no need to make comparison as long as the club is fine with both players.
