A man who epitomises this question among Gooners.
Some love him, some hate him, but there is no denying that Andre Santos is entertaining.
The Brazilian was another one of the clubs deadline day purchases, signing from Turkish giants Fenerbache for around £6m.
With Gael Clichy sold to Manchester City, Armand Traore moving to Queens Park Rangers and Kieran Gibbs seemingly always in the treatment room, Santos came into the side at a time when Arsenal were in dire need of a left-back.
Being a Brazilian, Santos received some criticism for his style of play.
The 5-3 win at Chelsea epitomised this after a few months of the season.
His desire to fulfil the stereotype of a footballer from Brazil was clear, bombing forward at every possible opportunity to join the attack.
He managed to draw Arsenal level on the day with an established finish after latching on to a smart pass.
However his defensive frailties were exploited.
There was no better example of this than in the build-up to Juan Mata's equaliser, where Santos' all-or-nothing style lunges cost the Gunners space and possession on the occasion, before the Spaniard launched a rocket past Wojciech Szczesny in the Arsenal goal.
Santos also came under scrutiny for his weight, often being touted as rather large for a raging full-back.
However, as the campaign went on, Santos seemed to trim a few pounds as well as his mistakes.
He also chipped in with a fair amount of goals; his equaliser against West Bromwich Albion on the final day of the season being the one that immediately springs to mind.
An on\off first season for Santos, who may be better off as an understudy to Gibbs.
Although, there is still the option for Arsene Wenger to play Santos further forward if he desired to.
