I wouldn't say I know him much more than most Serie A watchers because African football is not a standard on which to judge players for Premier League football. He is a good striker when utilized well, and I do rate him, just not as much as others seem to do.
He is one of the best strikers we have had in a while, strong, fast, good hold up play and hardworking, but you could attribute the same qualities to plenty of strikers out there without the same amount of hype, and he seems to miss plenty of games.
I'm generally not overly impressed by players dominating the Serie A, yet his goalscoring record in the league is mostly nothing to write home about which is my main qualms with the amount he would cost. Personally think we should pass.
