There really shouldn't be any excuse for not taking all 3 points. They're just not a very good team and aside from Sarr I don't think they have a PL level player. I guess Dennis seems somewhat useful but it's early. Cleverly, Sissoko, Cathcart, King, on and on, they are old and bad.
So yeah we're missing some important players, shouldn't matter. Just get the 3 points by hook or by crook and onto Atletico.
