"His numbers physically have improved so much. And he's willing, that's what I can tell you. He's been showing it in training. The structure has to help him to be able to take everything he has inside.
"On his own he cannot do it, he needs the collective and the structure around him and his team-mates.
"There's only one or two players in the world who can do it on their own. He needs help."

Arteta wants Xhaka to stay at Arsenal
Mikel Arteta hopes Granit Xhaka will stay with Arsenal as the new manager looks to revive the Gunners' fortunes.
Xhaka was stripped of the Arsenal captaincy in October by former manager Unai Emery following the player's angry reaction to being booed by Gunners fans.
He has since been linked with a move to Hertha Berlin in the German Bundesliga but Arteta, asked if he wanted the 27-year-old Xhaka to leave north London club Arsenal, replied: "I hope not. He played at Bournemouth, he played really well, he was very committed, he played a really good game.
"After the game he started to feel ill. He had a temperature and he wasn't feeling good. The last two days he was in bed. That's why he hasn't been selected."
