There has seemed to be no urgency to close a deal for a defender this week, with Txiki and Pellegrini probably feeling Garcia could 'fill in' until then. Today showed that Garcia can't 'fill in', at least not while Kompany is injured. Kompany can seem to partner well with anyone but once he's injured, we defend like a Championship team and it's a sorry sight. And like Mancini, it looks like Pellegrini doesn't believe two left-footers (Lescott/Nastasic) will work.
So whether it's Demichelis or someone else, they need to up the urgency and get someone in before the next game. If only Varane hadn't gotten injured, we may have had Pepe. We need an experienced defender with leadership and Champions League experience. Demichelis is still pretty good and might do a job, but if we want a high quality player in his prime, with leadership skills and the ability to organise a defence then I think Godin from Atletico would be better. He has been immense in the past year and is more mobile than Demichelis too. Either way, we need a second defender who can lead.
Lescott can't lead because he doesn't have the skill or intelligence, while Nastasic is just too young and inexperienced to be a leader.
