I'd also go as strong as possible with only Kelleher in place of Allison. Not just because we have a nice break coming up, but hopefully to try and make the 2nd leg redundant by getting a good lead heading into that.
So with the news of Trent I'd go with:- Kelleher, Bradley, Konate, Quansah, Gomez, Mac Allister, Elliott, Gravenberch, Jota, Gakpo, Nunez. I'd give Diaz a break and put him on for one of the forward 3 for 30mins or so.
