Xavi continues to do his best for Barcelona. Although various negative issues arose against him after achieving a series of poor results in the Champions League. Xavi's position as coach of the Blaugrana in my opinion is still safe, because Lewandowski still looks impressive in La Liga and is still in tight competition with his eternal rival Real Madrid. However, Barca need to adjust to new players.
Lewandowski is a striker that is not common in La Liga with too powerful fitness. Therefore clubs there have difficulty to prevent him scoring goals. He is still one of best strikers even his age is no longer young. With Lewandowski, give him half of a chance, he will be able to score goals.
Many fans have high expectations of Barcelona, but I think that's too cheeky. The reason is clear, Xavi is building his team and is constantly trying to give the best out of every match they play, but they didn't expect success to come so quickly for a team previously dying of financial problems and poor form. It takes time and sacrifice, just enjoy the upgrade.
They are unrealistic about the strength and competitiveness of Barcelona. They must recall just one and two seasons ago, there were a crisis in Barcelona. It was resolved by Xavi in second half of the past season. Xavi came and reunited their players, improved their performance and at the end, magically they finished at the second position. That achievement makes Barcelona fans think that their club is strong enough to win La Liga. It is not true and unrealistic for a club that is rebuilding like Barcelona.
