On their improvements, he said: "Absolutely yeah, absolutely. Clearly, clearly. As clear as you want it to be. 20-20. Definitely. 100%.
"Because of what I see. Playing our football, measuring ourselves against the best. The players have a real belief in what we're doing. That's all I need to see.
On wanting some of his players to be more like Cuti Romero, he also said: "Well we've only got one World Cup winner in the building so it takes a bit of time. And it's not about hunger or fight, it's just about a self-belief that Cuti has because of who he is and his journey up until now.
"The others, or a lot of the others, are just beginning that. But Cuti's had his painful moments in his career but he's learned to get through them and he showed the way forward on Sunday.
"So that's all I meant. Some of it is just growth of individuals as people. Which again you can't fast-track. I thought Cuti - he's been great for us all year - but on Sunday (against Arsenal) I thought he really lead by example."
