Nasri coming on made a difference, but only because we had no one to pick him up in midfield. They were just strolling past our midfield trio (even Stevie who's not quite upto speed of course). But Adam and Henderson we know are defensively inept.
Jays marshalled better players than Samir Fucking Nasri, and had he been on, I reckon we'd have controlled things a lot more in the second half.
We need a strong defensive presence in midfield even against the poorer reams (see Blackburn at Anfield). If Jays not fit, I reckon we'd need to see Agger step forward for a bit, because with both our defensive midfielders out, we will lose goals.
