After missing the previous few matches through illness, Mesut Ozil was left on the bench for Arsenal’s FA Cup quarter-final clash against non-league Lincoln City.The German was absent for the 3-1 defeat to Liverpool last weekend and was also a substitute during Arsenal’s 5-1 thrashing by Bayern Munich in midweek.However, he was called upon after just 27 minutes against Lincoln when Alex Oxlade-Chamberlain limped off with what appeared to be a hamstring injury.At the time, Arsene Wenger’s side were struggling to get a foothold in the game with the scores still level at 0-0.But, with the help of Ozil, the home side finally made the breakthrough before half-time as Theo Walcott’s deflected strike found the back of the net.Up until then, Lincoln had looked dangerous on the break and rather comfortable in defence.But Walcott’s strike in first-half injury-time effectively killed the tie as we saw a much more confident Arsenal after the break.Goals from Olivier Giroud, Alexis Sanchez, Aaron Ramsey and a Luke Waterfall own goal consigned the Imps to a 5-0 defeat.While the scoreline might not have been too surprising, there was a moment in the second-half that shocked everyone - the officials not giving a free-kick for the most blatant foul ever.Ozil - who Wenger may have feared playing against aggressive non-league players - barged into a Lincoln player right in front of the linesman towards the end of the match.Incredibly, the German got away with it and was allowed to bring the ball out of defence.It left BT Sport co-commentator Chris Sutton is absolute disbelief.

Ozil's 'tackle'

Take a look:

And Twitter couldn’t quite believe it, either. Check out the best reaction:

Ozil is considered a world-class player but the physical side of his game is often criticised. It seems as he’s been doing a bit of strength training in recent weeks, though!

Ozil and Wenger will just be happy to have progressed to the last four the FA Cup and avoided a humiliating result after a difficult few weeks.

For now, their focus will now be on trying to finish in the top-four - something they have done every season since Wenger took over in 1996.

To face an almighty battle to do so as they currently sit fifth as face fixtures against Manchester City (H), Tottenham (A) and Manchester United (H) before the end of the campaign.
