Arsene Wenger's side are now second in the Premier League table and left-back Nacho Monreal reckons the positivity in the side has helped produce their consistent form in the second half of the campaign.
The north London club have won 15 in 17 matches in all competitions and go into their tie today against Burnley at Turf Moor with six straight Premier League wins.
And, Monreal says the Gunners are 'bursting with confidence at the minute.
“The dynamic around the place is very positive and we have been able to beat teams both at the top and bottom of the table,” he said, as Arsenal.com reported.
“We are picking up points and playing well. That’s the general dynamic around the place at the moment - one of positivity.
“We had quite a difficult start to the season and those points we lost earlier in the season are proving to be a bit of a problem for us now. We are going through a very good spell now and the team is doing very well.
“We are bursting with confidence, playing very well and I think that is the vein in which we need to continue.
“We expect a very tough and competitive match. They are obviously in the relegation spots and obviously they are going to want to get out of that position.
“They will be playing at home in front of their own fans and of course they are going to want to try and beat us. So we are expecting a tough match.”
