Despite being an important keeper for the side (he has made 28 appearances so far this season), Roma seem to be thinking about selling Pau Lopez. In recent weeks, he has been criticised by several people including Franco Tancredi. The former Roma keeper called him a "normal" goalkeeper and that he did not like him.
This amount is necessary so that Roma do not incur losses. They need to get some of the 30 million they spent on him from Betis.
