I think our attacker are pretty good. We are one of the top scorers in the Serie A as a team without having the most creative mid field..
Back in the days when we had Zidane as a creative mid fielder with Inzaghi up front, Zidane used to give 20 Chances a game to Inzaghi so he can score 1 or 2 at the max.
Then we sold Inzaghi and Zidane and got Trezeguet (ok we had him before as a sub) Nedved. Nedved at his best created less chances than Zidane, though he maanged to score himself more than Zidane did, but trezeguet was a better finisher than Inzaghi. This combination allowed us to be able to score goals. Infact when both were performing well we were the highest scoring team in Serie A (along with best deffense).
This season we played most of it without Trezeguet with mainly Del Piero and Zlatan upfront witht he help of Zalayata. We still managed to score quite a number, which means our attackers are quite good whether they are finishers or supporting attackers.
I bet if we can bring up creativity into our mid field with keeping the attackerst the same we would end with one hell of a scoring machine.
