Ozil has been in impressive form this season and set a new Premier League record when he provided seven consecutive assists for Arsenal earlier in the season.
“Him [Ozil] and Alexis are the game changers,” Tomas Rosicky told Arsenal Player.
“Both of them have the strength to win games, so it’s vital for the team’s title chances that they perform well.”
Ozil now has six goals in all competitions this season as well as 16 assists in the Premier League.
Sanchez meanwhile has found the back of the net 10 times in all competitions. The Chilean international is back to full fitness after missing two months with a hamstring injury.
Arsenal are currently joint second in the Premier League with Tottenham on 48 points each. The London based side is five points behind leaders Leicester City.
The North London based side have the opportunity to reduce the gap to just two points when they take on Leicester this weekend in the league.
