Despite injuries to key players, Mertesacker says Gunners' morale is high as Arsene Wenger's team takes on Burnley in FA Cup tonight
London: Per Mertesacker says team spirit has never been so good at Arsenal as the FA Cup holders prepare to host Burnley in the fourth round of this year's competition tonight.
Arsene Wenger's men are looking to continue their bid to win the tournament for a third consecutive year but come into the game on a three-match winless run.
The Gunners drew against Liverpool and Stoke City before suffering a home defeat against Chelsea on Sunday in a match that saw Mertesacker sent off in the first half, ruling him out of Burnley's visit due to suspension.
But the former Germany international, 31, insists morale is as strong as ever, with the team still in the running to win three competitions despite a number of key injuries.
"We have kept the same squad and obviously made some great additions over the past two years," Mertesacker told the club's official website.
"In general, the team spirit has grown a lot. We are competing at the top and that is something that was not always the case when I joined.
"The team is much stronger and mentally stronger as well."
