Milan have already signed Luka Modric and Samuele Ricci, and were very close to signing Xhaka as well. But with Erik ten Hag's appointment at Bayer, the situation has turned a bit complicated as the Dutch manager also has plans of rebuilding his side with Xhaka being a top priority in the midfield.
Meanwhile, Guerra is tied to Valencia until 2027. Milan had previously offered €16 million (£13m/$18m) for the midfielder which was swiftly rejected by the Spanish side. However, with Guerra's contract extension coming to a halt due to wage issues, Milan can propose an increased bid for the Spaniard.
