Arsenal boss Arsene Wenger admits they missed Santi Cazorla for their 0-0 draw with Middlesbrough.
Cazorla sidelined due to an Achilles injury and Olivier Giroud suffering from a problem with his foot, but Wenger did not want to use their absence as an excuse.
He said: "We always miss Cazorla. At home, from deep midfield into the final third, his pass is always quick and accurate.
"We didn't make enough from our set-pieces and our crosses so of course, the first thing that comes in mind is someone with a bit more size and a physical presence could have helped.
"We have just come out of six straight wins and I would not like to use (the injuries) as an excuse. We are an offensive team and we didn't manage to score, which is frustrating.
"Cazorla I don't really know, we need to see how he recovers on Monday, but Giroud could be in the squad on Tuesday night."
