Arsenal defender Thomas Vermaelen says the new signings have made a difference this season.

The Belgian also senses a renewed self-belief amongst the players since embarking on their winning run.

"I think it [momentum] just happens," he told Arsenal Player. "If you are winning games then you are in the mood, you are positive and your confidence just goes up. That's what's happened with this team.

"Maybe because we had a bad start some of the self-belief wasn't there as much for some players but when we started winning again it came back. That's why we're more confident on the pitch and we'll get better results.

"It's hard to say which moment or which result but I think the new players have been really important for us. They're doing a great job at the moment and they bring experience.

"People like Mikel have played a lot of games in the Premier League and Per has played a lot in the Bundesliga and for his country. Both are really experienced and I'm really happy with them. That was good for the team I think, when they settled in well, and we've been getting better results."
