The Polish star Robert Lewandowski expressed his disappointment over Barcelona's Champions League group stage exit but he remains hopeful of a turnaround soon. Speaking to Global Goals website after his side's victory over Valencia, Lewandowski said: "Obviously I’m not happy, Barcelona should be in the last 16. But before I came to Barça I was already aware that the first season could definitely be more difficult than it should be. "We are in the process of rebuilding which takes time, we must be patient. I’m sure these setbacks will make us grow as a team and that everything will be different next season. We are evolving. I wasn’t expecting to arrive and that everything would go well in season one. I insist that it is a process that requires time and patience." FC Barcelona and Viktoria Plzen will face up this Tuesday, November 1 at the Doosan Arena. The match corresponds to the sixth day of the group stage of the 2022-2023 UEFA Champions League and pits Michal Bílek's Plzen against Barça coached by Xavi Hernández. The Spanish giant will meet Viktoria Plzen after that in their last match in the group stage of the Champions League before they face Almeria in La Liga on November 5.
