Robert Lewandowski has played very well for Barcelona which is big surprise to many people. He has scored many goals and is best scorer in Spanish league for last three years. It would be good idea for Barcelona to give him new contract because he is still playing at very high level. Lewandowski works very hard and loves game which is inspiring to see. He definitely deserves new contract if he wants to stay with Barcelona.
Robert Lewandowski already had a contract extension, Barca used it. But they are looking for a new striker to have an alternate to him. Because he is of a certain age. Okay, there are strikers who are still top scorers and play at a high level after the age of 35, but aging is a part of life and you can't be as physically strong as you used to be, even if you want to. You are more prone to injury and it takes longer to recover. Barca can't afford to have their main striker so old when they are competing at the highest level. Lewa can be a backup and an alternative in the future. Every team wants a superstar striker like Lewa in their squad. It was obvious that Barca wouldn't let him go.
