I'm not too excited about this one, but also using the '27, Portuguese League' argument to suggest he's not up to the level seems odd given how Bruno has turned out.
Think he'll be a good squad option, and gives us more variety. We can go 5 at the back now in certain situations, with Shaw as LCB and Telles LWB. Also, Williams can provide cover to AWB now ans we can move on Dalot.
Think what's noticable with the potential signing of Telles, and the signing of van de Beek, is they both have plenty of CL experience, as Ole knows we're going to have to rotate and having experienced heads to bring in is important.
