Lewandowski is not a bad player, and Barcelona's desire to get rid of him this summer begs the question of who they have on the list or want to sign to replace him in the striking role. Atletico Madrid's acquisition of Lewandowski will benefit them in both the La Liga and the Champions League, as the player, despite being in his 30s, is still performing well and can do wonders for his team. If Barcelona loses him this summer, which I doubt, Atletico Madrid can add him to their squad, strengthen their forward position, and be ready for a better chance to win a trophy sooner.
Lewandowski is one of best strikers in last 20 years and he was disappointed that Bayern Munich didn't give him a long contract so he decided to leave and move to Barcelona after his contract with Bayern Munich expired.
In his first season for Barcelona, he helped them to win La Liga and won the Best Scorer Award too. His contribution for Barcelona last season is amazing but he is already old and Barcelona actually aware that at his age, his contributions can suddenly drop a lot.
This season is going like this, he is older, get more injuries and has less appearances and contributions for Barcelona. With 13 goals scored for Barcelona in La Liga so far, it's not too bad stats from Lewandowski and he is only 3 goals less than Jude Bellingham. Lewandowski is able to score 2 or 3 goals in a single match and he can catch Jude anytime.
