Napoli new coach Walter Mazzarri continues to try to stabilize the team. But so far the performance of Napoli is not stable. After Walter Mazzarri became coach, Napoli played 7 matches, won only 3 matches and Napoli lost 4 matches. So Walter Mazzarri should not be trusted too much. The overall performance of the Napoli team is still quite weak.
On the other hand, Barcelona team is not doing well in La Liga. They share points with Valencia. Barcelona won 3-2 with Almeria. However, in the last match, Barcelona lost 3-2 against Club America in a friendly match. Barcelona's team's performance is understandably erratic right now. Looking forward to see what steps coach Xavi takes to strengthen the team.
Walter Mazzarri is trying to repair the mistakes made by Rudi Garcia, it's not easy to fix something broken, especially if the team doesn't have a strong character and can't resist bad moments, as Napoli are experiencing now
This remains a very difficult thing to do, to rise from the ashes, but to be honest I have seen an improvement. Obviously we can't expect him to fix everything right away, he doesn't have a magic wand.
