Romero is still young and he's had to adjust to some brickshow of a defensive unit, let's see how he does under Conte. As for Dier, simply not good enough for Spurs. I get that he was played as a DM under Poch and all that so he didn't have the benefit of developing as a proper CB, but this is his preferred position and you have to be cool and commanding as a CB, which I would say he's neither. He hasn't been utter dogbrick-tier, just saying he's not good enough. I find that a lot of people here get very defensive about certain players (dier, dele), but again I have to repeat, I think most of us that criticize any player don't want the player to keel over and die; we just want some improvement and in a leaky defense, the GK and CBs should be the first ones who need to be inspected... and I do think Lloris has been part of the problem as well.
