I just hope Robert Lewandowski get back to his full potential like that at Bayern Munich were he could be able to score several hat tricks in one season, ever since he came to Barcelona I've not really been impressed with his performance compared to when he was at Bayern Munich, Barcelona are known to be very dominant and very high in possession on the pitch, they love to press their opponents and force them out of their defense line which is a very fine tactics that could make them easily win matches against smaller club but you'll find them pressing and failing to put the ball into the net, and it would fall back to Lewandowski inconsistency for Barcelona, since he's the top 9 it's his responsibility to get the ball into the net but it's been uneasy for him instead it's the Barcelona wingers and Midfielders that mostly scores for them.
Don't rely on it. He is already 35. I will be surprised if he still plays in Europe next season. I think he is in decline and it began in Bayern (it was not for nothing that Bayern did not want to sign a long-term contract with him and only offered him a year), but we did not notice this because Bayern itself was fine. In Barcelona, this problem manifested itself and given the fact that Barcelona’s affairs this season are not as good as in the past, it is unlikely that Lewandowski will show himself better.
