In the end Barcelona won the match. Sevilla's players performed well in this match. Made a lot of attempts to score. Most of the attacks are done by team players. But Sevilla do not have enough experienced players in their attack. This is why Sevilla can't score more than one goal despite attacking a lot. Sevilla have scored just 48 goals in 38 matches this season.
Barcelona played very carefully in this match. Xavi is well aware that Sevilla's attack is not very strong. So Barcelona didn't try to attack much after scoring their second goal. Barcelona played somewhat defensively. And eventually managed to win the match by 2-1.
It was difficult to accept that this was Xavi’s last match in Barcelona, but if you look at how he comments on his dismissal, it seems to me that he even talks about it with relief, as if in the end he got what he wanted. Since Xavi was fired unexpectedly, there are no rumors yet where he can continue his career, but I think that he will quickly find a new club where he will be the head coach, he has achieved good results in La Liga, so there will be many teams, that willing to work with him.
In the end, this victory could be a farewell gift for Xavi, although it cannot be celebrated on home turf. It's quite sad to see Xavi have to leave Barcelona because it's not just looking at his contribution as a coach but Xavi has very strong ties to Barcelona and it was in Barcelona that Xavi grew into a great player.
His Loyalty to the club and its supporters, which made him make a U-turn to continue coaching Barcelona apparently couldn't save him from the wrath of Laporta who suddenly fired him for an unclear reason. Well, this is the path that Xavi and Barcelona must take, even though I know there are some who regret that this happened.
