starting a CB pairing that haven't played together yet against the best striker in the league will end well.
It's not like we've had any consistency back there all year anyway and we've acquitted ourselves fine. Plus 2-3 of them are injured anyway. Otherwise, Vertonghen is obvious first choice. I'll take the matchup over continuity in this case. Vlad (if fit) and Capoue have the athleticism to attempt to knock Suarez off his game.
Then bring back Daws to combat Osvaldo/Lambert and whatever lump West Ham puts up top. That's the beauty of all the depth that we have now, we have a variety of players who do different things so we can tailor our lineups to whatever opponent we play.
For playing a possession based team with a quick striker like Liverpool I think playing a guy like Capoue who had four interceptions last game makes sense.
