We will see next season if Xavi is able to maintain his good performance next season. Next season, several targets may become a big priority for Barcelona, one of which is to win the Laliga Trophy from Real Madrid. Barcelona is now looking for a solid sticker figure for next season. Lewandowski is their target and I think the hopes of the Barcelona fans to see Barcelona go wild in front of goal will come true again if Lewandowski comes to Barcelona.
The target for Xavi is actually to improve again the performance of Barcelona, by adding more professional players and also improving the players that have been in the club. He must learn more to get the best tactic in order to get more points in the next season. Moreover, Barcelona is qualified for UCL< Xavi and his team must be very excited for this, they finally can feel again the euphoria of UCL.
