I guess I can see his pros - starting with, he is not slow, and not slow mentally, unlike as much as I hate to say it Balotelli or Lambert or even Borini probably will ever be. he is still 24 until the end of the year but has spent 3 seasons in England with decent numbers which I'm looking at, 10+ goals in each season (23 11 13), he is strong, he is technically good, he has desire and can score good goals. for me he has caught the eye, he annoyed me when he came on for petty reasons but I noticed his talent for sure.
Villa play 4-3-3 or at least Benteke alone basically up front yeah? For some reason I see something like Coutinho - Benteke - Firminho/Lallana working, with the backing behind them. He seems to be able to hold his own, create his own goals, work for the team (+ GENUINE THREAT IN BOX). We need someone who can come in from match day 1 and start up front with guys buzzing around him. I think the club is looking to stay within England using a bit of the 'Prem proven' crap, but I see some logic in it, the 'risk level', among other things. I guess. He does have a good record to back himself up though.
Now I've just watched highlights of LFC 1 - 3 Villa from a few years ago where he scored 2 and assisted 1, granted we had a shit team then but so is Villas team most years

plus he is 21 in this game and already looks like a bull. I am starting to like him now.
