The 27-year-old joined Arsenal from Real Madrid back in September 2013 for a club record £42 million and helped Arsenal break their long wait for silverware with back-to-back FA Cup wins.
However, the north London based club have live up to fans expectation after missing out on a chance to win the Premier League title.
Dixon believes that Arsenal must show Ozil that the club are ambitious enough to compete for top honours next season.
“Leaving Real Madrid for him was a big thing,” Dixon is quoted as saying by the Daily Mail.
“He wanted to come to a club that could play in Champions League at a high level and win something. He is now looking at the club.”
“The next transfer window is very important for him mentally. If he sees Arsenal are making a real effort to trying to build a side like Real Madrid, he’ll be happy.
“He is possibly one of those players who could lose it at any moment and think he needs to be playing at a high level and win trophies.”
Ozil has recorded 18 assists and with two matches left this season he still has a chance of matching the Premier League record of 20 set by Thierry Henry.
