I have seen ur other post saying we don't need a lb, a mid instead...i kinda agree...but Alaba is still only 28 , transfer fee should be relatively cheap....so I would be happy to have him and more importantly his UCL winning experience here.
Alaba could play midfield for us?
He has all the attributes to be a fernandinho.
Also if he did play inverted LB it would be very similar to the system we played vs. Wolves with Alaba and Rodri as a 2 sitting in front of Laporte-Dias-Walker.
That feels like a really solid back 5.
