Worth it because so far Robert Lewandowski has become one of the best players in the Bundesliga. Speaking of numbers, at least it's estimated that Barcelona will get what they paid for.
Barcelona did that, offering to bring Luis Suarez back to Camp Nou from Atletico Madrid but the result was rejected by Luis Suarez. And that's a natural thing in my opinion as a form of disappointment over Suarez's loan agreement to Atletico Madrid some time ago.
Barcelona desperately need a striker to complete it next season, and no other name than Lewandowski is being targeted.
It is obviously good that Barcelona is really serious about their improvement as a team. But spending 50 million for a player who is 34 also under the current financial situation of Barcelona is in no way justifiable. We have seen Barcelona bring in Philippe Coutinho for a huge amount of money and that backfired really badly. Yes, sometimes transfers can go wrong and not produce the result that is expected but right now is it worth taking the risk and spending 50 million on a player who might not give a service for a long time to the club.
