Mendilibar's time has ended at Sevilla recently and Diego Alonso has been appointed to the manager position. Sevilla have started to change their manager very often in the recent times. Sampaoli, Mendilibar and now Diego Alonso... I don't believe this is a good action to take for a team.
Because the system mostly changes and the players have to adapt to the new one every time. They have to get along with the new manager as well. Rather than that I think Sevilla should have given it some time. They won the Europa League title with Mendilibar in the end.
Mendilibar has not improved the performance of the club in any way and that is why the Sevilla government has decided to Mendilibar go because it is looking as if he is out of idea letting him go was the best they could do is to let him go, Diego Alonso has been their new head coach I hope he comes with determination and strategy to improve the performance of the club because some times some coach find it very difficult to identify were the problem is coming from. look at Sevilla's current position on the La Liga table it will even become more difficult for them to change immediately it will take some time before changes start coming.
