Eric did brought Manchester united into bright light,he was able to discipline the players and built a team that is very strong and superb. It is Eric vs Xavi on the match day as both coach will want to show their quality that they have all it takes to win the match. Barca are performing excellently which will not make it easy for Manchester united to win the match. If Lewandoski is macked out it will be a problem for the club since De pay is gone.
Since Depay has already left, I'm sure they're looking for a plan B. The worst-case scenario for Barcelona is that Lewandowski is injured before their match against Manchester United. I'm not saying they won't have a chance, but they'll face a lot of pressure from Manchester United, as well as a goal drought because they don't have a striker who can simply finish the game for them when necessary. This is supposed to be a tough match, but given the present state of things, we may have to just see Manchester United prevailing against Barcelona.
Barcelona versus Manchester United match is going to be quite difficult for Barcelona. And I do not know what Barcelona is going to do if somehow for some reason Robert Lewandowski, who generally does not get injured for long periods of time, does end up getting injured.
Barcelona will not have a proper striker if that happens. As long as Barcelona have Robert Lewandowski on the team, I do not think they will have to worry. But it will be better if Barcelona does keep a replacement for Robert Lewandowski. Obviously, they are not going to find someone like him. But they will have to get someone who will be a good substitute.
