It's not worth paying 40 million for a player who is already 34 if the player is not Lewandowski. Why? because behind Lewandowski's 40 million price, there are other goals that can give Barcelona profits, in my opinion, such as selling jerseys and other merchandise.
It is impossible for Luis Suarez to return to Barcelona because the basis of Suarez's sale to Atletico Madrid is because he is no longer young and Barcelona needs younger players because of Barca's busy schedule. I think you still remember the reason why Barcelona officials let Luis Suarez off a few years ago.
I also agree that Barcelona needs young players to get ready for the future but I don’t think buying Robert Lewandowski is a good decision because he is also not young either. If he was 27 or even 30 years old, paying close to 50 million would have made a lot more sense to me but now it doesn’t really make any sense. For 50 million I think Barcelona will be able to find younger players. And they will be able to give their service for a longer time to Barcelona than Lewandowski. But I have to agree that the play style of Robert Lewandowski is going to help Barcelona a lot.
