England and Arsenal midfielder Jack Wilshere is hoping a line can now be drawn after he admitted making a mistake by smoking a cigarette.
The 21-year-old was photographed smoking outside a London nightclub in the early hours of Thursday morning as players wound down following Arsenal's 2-0 win over Napoli, with Arsenal boss Arsene Wenger later criticising the England international.
Despite the incident, Wilshere was recalled to Wenger's starting line-up for Sunday's 1-1 draw at West Brom and scored the equalising goal which took Arsenal back to the top of the Barclays Premier League table.
"I've learnt that you've just got to concentrate on your football," Wilshere told a press conference.
"You're a footballer at the end of the day and when it comes to the weekend you've got to be ready.
"Players and young people make mistakes and I made a mistake.
"I spoke to the boss (Wenger) and we sorted it out and he put me in the team on Sunday and hopefully I repaid him with a goal so hopefully it's all done now."
While he has learned a lesson off the pitch, Wilshere, who has represented England at Under-16, Under-17, Under-19 and Under-21 level as well as the senior team, says he still has a lot to learn from experienced team-mates Steven Gerrard and Frank Lampard.
"As a young footballer I have grown up watching those two and you can learn things from both of them," Wilshere said.
"The way Steven Gerrard passes the ball, his range of passing and how he puts his foot in and the way Lampard gets forward and his goalscoring record speaks for itself so I can learn from both of them."
Back-to-back victories against Montenegro on Friday and Poland next Tuesday will sweep England into next year's World Cup finals in Brazil.
Four points would also be enough if Ukraine fail to overcome Poland in Kiev on Friday, but anything less and England will find themselves in the play-offs or, even worse, eliminated altogether.
However, that is not something Wilshere is contemplating and he is confident with the strike force England has to offer.
"We have got Sturridge and Rooney back which is going to be massive for us as you want your best players available," he said.
"Rickie Lambert has done a great job. He scored a couple and did well in Ukraine which was a difficult place to go and be up there on your own and do the job he did, he did really well.
"We have got Defoe as well who can score from any position and Danny Welbeck as well who is looking sharp. We have got a good mix there and it can only be helpful for us."
Despite England's unbeaten record, Wilshere knows that is not the be-all and end-all when it comes to qualification.
"It's nice to be unbeaten but we can still be unbeaten and not go to the World Cup," the midfielder added.
"We don't want that. We have got two big games ahead of us and that's the way we've got to look at it.
"We need to focus. We will look at Montenegro and look at their strengths."
England defender Phil Jagielka is also confident that Roy Hodgson's side can cope with the task ahead.
"I was there when we drew the game away at Montenegro, as a team they've got a fantastic unit together," said Jagielka.
"They put us under a lot of pressure, they are progressing and they're confident as well.
"They're going into this game as confident as us due to the fact they've picked up draws against us before, and they're still in with a chance of trying to qualify themselves.
"We all know the task that lies ahead. I think there are quite a few people who've got the experience of being in similar situations before, so they've got big roles to play.
"We've also got some young lads with fantastic ability, so we're massively confident we can go out there and put on a good performance which can hopefully produce goals."
