Colwill will learn from that struggle against Brobbey. You don't get tight to fight with a striker who is bigger than you. Also, the technical staff will now understand Colwill's limitations. That is part of squad and player development.
Alonso will know Colwill better and will be ready for Brobbey with a different profile or will prepare Colwill specifically to handle him differently.
Do you remember Davies vs Reece in the Champions League during Lampard's reign? Reece was destroyed like I had never seen, but since then, no winger or fullback has done that to him, not even prime Vinicius.
Already firmed the L. Players off it performance wise and the referee clearly is out of his depth.
We clearly canβt deal with physical sides away from home. Especially the ref endorses a lot of it.
