Sometimes even the most experienced and best coaches lose a game and this shouldn't be a reason to say Arteta is the reason for Arsenal to losing in the Europa League, nothing is predictable and this time Arsenal lost Eurpa lege while I mean thinking they can even win the title this season with Arteta because the performance they had during this season, but now I guess after Arsenal Manchester United is the first hope.
Yes this is Europe, there are many surprises. In fact, look at Barcelona, they are very good, but they are not effective in Europe. So in this sport there is a guarantee for a team that looks good in the league can be successful in Europe. Arsenal with Arteta was the best season after they played poorly. They may not be too sorry about missing out on the European championship chances because they currently have a great chance of winning the EPL.
