Not only TAA for now because indeed some players like Salah and Van Dijk are also still quite worrying for Liverpool because they have not been able to make an agreement on a contract extension.

Madrid seems to want to try to do a good rotation especially with Carvajal's current age which is already quite old plus his coating Vazques who does have the same age, so indeed looking for other options such as TAA is very good.
It's just that there has been no further confirmation of this, but if indeed TAA plays in Madrid and for the other side is filled by Davies, which has been rumored since the transfer of players last season, it will make 2 full-backs Madrid become very crazy because indeed both have good attacking power and their speed is not in doubt.
