Would personally take more than just him. Players like Firmino, Lallana and Henderson (I've never rated Henderson but he's looked much improved) have shown more than just more fight and desire. They've shown actual quality and an ability to score and create.
They have, and it's all down to the manager. He's given them that belief and unity. Ferguson was the same, he could the best out of players.
He's a yellow toothed bell but I'd sell everyone down the river to have him manage us
