I agree with that, I'm just saying that your tactical options are being limited somewhat by having your two best strikers fitting a similar mould.
You're still lacking a striker who can run in behind. Walcott can do it, but last season made it quite evident that Wenger still sees him as a winger. My surprise is that you haven't gone for a quick striker who offers a different option.
On the other hand, with Higuain on the market at that price, he is a very good signing. It just depends on who else Wenger will sign/could have signed.
Giroud and Higuain aren't the same kind of striker, at all, and Higuain is the kind of player who gets in the box for tap ins, he's just also good dropping deeper and pulling out wide. When we see Giroud go wide with the ball, he loses it almost every single time, Higuain can whip a killer ball in, Giroud can't.
Giroud is a target man, get the ball to him with his back to goal, pull the defence out of position then play a ball in behind. Higuain is the guy who makes the run a Giroud type passes to.
Higuain is a capable player but if I were to class him as a specific type of striker, it would be closer to Defoe/Hernandez than a deeper playmaker style of striker, no question. I wouldn't be surprised to see it not happen, and I wouldn't be surprised to see it go wrong.
Playing Walcott upfront as a player to run in behind, he has zero intelligence, he's got rubbish timing, just as a wide player he is less the focus of the cb's and gets more chances to make runs in behind, as a "main" striker he's VERY easy to mark and is also pretty terrible coming directly at goal, he has one successful type of strike the pass into the far corner, put him running through in the middle of the pitch, and he screws it up 9 out of 10 times, he's clumsy and daft, he usually tries a tame pass style shot form distance or just misses the target, he rarely takes it round the keeper because his close control is pretty awful.
he'd score less as a main striker and only has the "success" he has played out wide. Remember he did play upfront, Arsenal failed to dominate any of the games, we were terrible, fluked a few wins on penalties against teams not playing very well. He was woeful, yet keeps insisting that the goals he scores while playing wide, are proof he should start in the middle... when he doesn't score the times he's started in the middle. Kid's an idiot and doesn't care, he was just using it as an excuse to persuade Arsenal to put up a big wage offer otherwise he'll look for a club he can play as a main striker.... Wenger fell for it.
Fellani.... please god no, 11 goals or something makes a great season..... he played a significant portion of it as a striker and deserved at least a few red cards throughout the season. Thug without much actual talent, and Everton score from set pieces without Fellani... Baines would increase our goal scoring threat at set pieces, Fellani won't, our problem is getting the ball into the box not who is there.
