Dumfries is benched permanently by Darmian now. Only started twice this season. We really need an upgrade over him. It will not take long for Frimpong to start over him in the Dutch NT. Giving him an extension at 4 mln a season means we ar stuck with him for the coming years. I’m honestly in doubt if it isn’t better to let him go for free coming summer at this stage.
I'd be inclined to agree, however I think from a squad building perspective you don't want to have to change both players in a particular position in the same summer. This probably should be Darmian's last useful season so they will need a new RWB and Dumfries for continuity.
