I don't think our team works that way. Your best three defenders can all expect to see fair share of game time without anyone being needed to be labelled as 3rd choice. Matip has played so much over the past few weeks that I'm sure even he wouldn't have expected at the start of the season - and he is fourth choice. Secondly, if Skriniar cannot trust his ability and back himself up to break into the team, then I'd rather not have him. You've got to have faith in yourself if you ever want to be a to footballer.If only. Why would Skriniar come here to be third choice? I appreciate that Gomez has injury concerns but he has to be Virgil’s partner when fit.
I think we have forgotten what it means to be a really really top side. Look at city, Barca, real etc, all have deep squads with depth in quality. We can't keep shying away from adding top quality players just cuz they will be 'third choice'.
