The aerial presence was simply not good enough against Southampton. Despite Graziano Pelle being extremely talented in the air, Mike Williamson would have offered a more secure opponent for the Italian. Chancel Mbembas heading ability will continue to be a concern if he is going to be paired with Fabricio Coloccini, as was demonstrated for Southamptons first goal. He is a like-for-like for his Argentine teammate - rather than a Mike Williamson replacement - and the pairing were disorganised throughout the match.
