Arsenal fans can breathe a huge sigh of relief - Mesut Ozil is OK.

The Gunners were a little worried after Ozil was substituted in the World Cup qualifier for Germany against Sweden after the playmaker seemingly picked up a knock on his knee.

Initial reports suggested that there wasn't too much worry and it was just a minor issue, and the same has been confirmed by Arsenal manager Arsene Wenger.

"He is alright," Wenger told the club's official website. "He came back with a knock on the knee but it was just a kick. We'll have a test tomorrow (Friday) to see if he is fit enough for Saturday or not. When you have not played, there is always a little doubt but not a major one."

That dream partnership between Ozil and Santi Cazorla is also moving closer and closer with Wenger confirming the Spaniard's return to training.

Wenger also said Bacary Sagna has a chance of making the squad which will face Norwich at the Emirates on Saturday when the English Premier League returns after a two-week break.

"Cazorla is available in training but he is not match-fit," Wenger said. "It is just about competitiveness with him. Sagna is 80 per cent fit and he will have a test. There is a possibility both are in the squad for Saturday. I have not decided whether they will start or not."

Wenger could decide not to risk Sagna, with a readymade replacement in Carl Jenkinson available, although the Frenchman will be tempted to give Cazorla a run, if not from the start, then definitely a little later in the second half.

Theo Walcott was also expected to be ready for action soon, but Wenger confirmed the England forward will take another couple of weeks before making his comeback from injury.

Tomas Rosicky is fine, but Lukas Podolski, Yaya Sanogo, Abou Diaby and Alex Oxlade-Chamberlain are out for longer periods.

Wenger said he will take advice from the medical staff before deciding which player to rest and which ones to play on Saturday, following a potentially grueling international week.

"We start to look at it (the minutes each player has played) and you get their (the players') feeling as well," Wenger told Arsenal Player. "You add that to the number of minutes they have played since the start of the season, then you make your decisions.

"Overall we do not come off it (the international break) too bad because (Laurent) Koscielny didn't play the first game at all, Giroud played only one half and 80 minutes in the second.

"The only one who played again over the two games is Aaron Ramsey, and apart from that (Per) Mertesacker played only one, Ozil played nearly two full games.

"You look at it (the numbers) because we play so many games now. That's why it's important to have players like Cazorla, like Rosicky and hopefully Walcott, Podolski and Chamberlain back soon."
