Mesut Ozil is Arsenal's star man, Gabriel can't be a regular and Joel Campbell is not capable of filling Alexis Sanchez's boots - FIVE THINGS WE LEARNED

Mesut the maestro 
Mesut Ozil is out on his own as the Gunners' No 1 talisman.
The German international, who had already claimed a Premier League record with assists in seven successive games, kept the statisticians busy when he fired his side in front at Carrow Road. 
Ozil has now played a part in 13 of Arsenal's goals in their last 12 games – 11 assists and two goals, to be exact.

Gabriel can't be a regular 
Brazilian defender Gabriel Paulista remains a long way short of the standard required to claim a regular place in the Arsenal defence.
The £11 million signing from Villarreal in January was introduced early on when Laurent Koscielny was unable to continue after treatment and the first time a serious question was asked of him he made a complete mess of it, allowing Lewis Grabban to turn him far too easily for Norwich's shock equaliser. 
He was also close to conceding an own goal in the second half, only Petr Cech's alertness sparing his blushes.

Neil has what it takes  
When it comes to inspirational half-time pep talks Norwich boss Alex Neil can clearly compete with the very best. 
How else would you explain the Canaries' stunning second-half transformation that saw them roar back and give the Gunners an almighty fright? 
Relegation fodder? Not on this display they're not.

Campbell is no Sanchez
Joel Campbell, the Gunners' replacement for the crocked Alexis Sanchez, is not capable of filling the ex-Barcelona man's boots. 
Arsenal will be hoping that both Koscielny and Sanchez are not going to be sidelined for long as their absence will surely extend Arsene Wenger's long wait to recapture the Premier League crown
