Ozil's return from injury
It was the same story at the beginning of 2014/15 as well - Özil was criticised for going missing in the big games, such as those against Borussia Dortmund and Manchester City. His disappointment was so great that some even called for him to be dropped. It may have been a blessing in disguise when Özil picked up an injury that would keep him sidelined for two months.
After he returned, Özil looked considerably more fit, and eventually made his first start since injury against Aston Villa. Özil was arguably the best player on the pitch during that game - a goal, an assist and an excellent all-round performance. It was a sign of what was to come. In his first five starts since injury, Özil scored twice and assisted five more goals.
Almost in direct response to the criticism he'd received, Özil began to perform in the big games - he was superb in the 4-1 thrashing of Liverpool and summed up the performance with this gorgeous free kick:

He has fine dribbling ability, superb vision and is able to split even the toughest defence in two with an accurate through ball.
Statistics from Squawka.com show Özil's revival - he averages 3 key passes and 3 chances created each game, while he dribbling success rate has gone up from 50% to 64.2%.
Following this success, Gunners fans have huge reason to optimistic.

The combination of the reborn Mesut Özil with the likes of Alexis Sánchez, Santi Cazorla and Aaron Ramsey will be frightening indeed.
