Scoring goals breeds confidence, though. Without that, the rest of his game will suffer. You could say that Ba's all-round game didn't suffer last season during his drought, but he was still getting chances all the time. This season Cisse gets a chance or half a chance a game, if he's lucky. He's not just a goalscorer, but he needs to be allowed to be one for the rest of his game to click, imo.
I thought some of Ba's performances during his drought were atrocious to the extent that he looks a completely different player now to how he did at the end of last season. Looked like he couldn't take a first touch at times, sloppy passing etc.
Kind of like Cisse now.
As you say, scoring breeds confidence, he scores a few goals and his game will improve.
