German side Hamburg are assessing Amadou Onana's movements during the transfer window.

The central midfielder was sold by Hamburg to Everton in the summer of 2021.

A sell-on clause in that agreement means that if he is sold on by the Toffees, Hamburg get a piece.

Bild have stated that the German club are hoping a team makes a bid offer for Onana.

While Everton do not want to sell, there have been rumors about a bid from Arsenal.

The Gunners are very serious about securing Onana to bolster their title challenge, per various British sources.
