I think Liverpool's transfer decision is good and in my opinion, they are thinking long term. I agree that at least for now Luis Diaz seems to be a reserve player for Sadio Mané. Overwhelming Sadio Mané and taking his place just seem to be not realistic.
And Barcelona seems to find players falling on contracts because of their financial situation but I also think that for Adama Traoré, an alone deal is perfect for Barcelona. We also have to wait and see if Barcelona can confirm the Aubameyang deal too.
