Indeed it's Insúa.
Don't know why anyone would be a fan of N'Gog, though.
I'm no great fan of his but to give him his due he was scoring regularly last season (even under fool Hodgson) until he was replaced when the traitor 'recovered' from injury & lost out when Suarez & Carroll arrived. The rest of his game may be decidedly average but when he does get chances he puts a fair few away. He'll be a decent backup when others aren't available - if he stays like Mr. Henry has hinted at.
