Barcelona coach Xavi Hernandez confirmed that the door of the Catalan club is open for Argentine Lionel Messi to return at any time.
Barcelona will face Manchester United on Thursday, in the second leg of the knockout round qualifying for the price of the Europa League final.
Xavi said during Wednesday's press conference: "It's a very difficult game, Manchester is one of the best teams in Europe, they are doing a good job with Erik ten Hag, we have to show our character, our style of play, the mentality of competing in Europe."
"Yes, I settled on the starting line-up, but the idea doesn't change, and playing with more or less midfielders changes slightly."
On the absence of Pedri and Gavi: "I would like to highlight the absence of Dembele as well, and of course the absence of Pedri and Gavi is influential, but we have good alternatives."
On the possibility of extending the extra time, he commented: "All scenarios are possible, extra games and penalties, winning and losing, but our ideas do not change, where we will play to attack and possession of the ball, and make the opponent not feel comfortable."
"Sergi Roberto can play in any position, he is a great guarantee for us, he will definitely be an important player."
On Lewandowski, he revealed: "Strikers always need to score, but we look beyond goals, Lewandowski excelled in assists, he is a great player and changed our mentality and not only the team but the club as well."
Asked about Messi, he replied: "I have already said that Barcelona is his home and the door is open to him, and certainly this is his home without a doubt, and he will welcome the best player in history."
"The Qatari sheikh who offered to buy Manchester? I trust him and he is capable of doing a good job, and I know him because I spent several years in Qatar."
