I can't say if Chelsea has improved in their performance or not, it's when the new season starts is when we would know. However, their performance in CWC is impressive and their fate will be tested in the finals when they play against PSG who have destroyed and humiliated top big clubs in various leagues in recent times.
No need to remain neutral and not say that Chelsea’s performance hasn’t improved, it has indeed improved and they’re beginning to maintain that consistency in the game. Before the end of last season, they improved so well that they made it to the champions league for next season. It didn’t stop there and their beginning continued with that top performance in the club World Cup and are now in the finals. This is indeed a progress to them and will say they’ve improved significantly than before.
Remember that Anthony was actually good during his Ajax days of which Ten Hang was his coach then and when he moved to United he started looking for his previous players, lol. Anthony at Manchester United was just a shadow of his formal self because he did almost nothing in that team despite commanding such huge transfer fee. And now in Real Betis his playing good again and one would wonder what could be the problem. Their are different scenarios I can draw. Maybe his not suitable for EPL or maybe the team isn't suitable for him or his not that spectacular in facing opponents from big teams too.
Antony situation is kind of difficult to explain but he has really improve in all sense of responsibility as a player. Joining Real Betis was the best for him because his old self is back and looking very great once again. I don’t think he’ll be going back to Manchester United even after seeing an improved performance from him, he’ll likely end up in Real Betis and continue his best form there. I really admire the player and how he plays for this team. Some players just need a new place to showcase themselves better and maybe the Manchester United environment was not the best for him that time.
