Samir Nasri (Manchester City)
Another star player who Wenger did not really do enough to keep hold of is French international Samir Nasri. The 29-year old joined the English outfit back in 2008 at a young age, scoring 18 goals in his 86 appearances. He quit the Emirates in 2011 and went on to make more than 100 appearances at the Etihad. He has had a similar output in terms of goal scored and was an important player for City in their maiden title-winning campaign. Although he was not consistent for Arsenal, his experience would have gone a long way in negating the current situation the Gunners are in. He is now not a wanted man under Pep Guardiola but it is too late to even think about going back.
