Arsenal: Five key questions ahead of facing Tottenham Hotspur

Five key questions ahead of the North London Derby...

Arsenal head into the North London derby at the weekend on the back of a mixed run of form, winning one and losing two of their last four games in all competitions.

As well as having to deal with injuries to key players, and integrating others who are out of form, there are several questions to ask ahead of Sunday's encounter.

Who should play at right-back?

Arsenal's biggest dilemma in terms of team selection is replacing Mathieu Debuchy. Calum Chambers started in the win over Aston Villa at the weekend, while Hector Bellerin has played at right-back in defeats to Dortmund and Southampton. That win-loss record may tell you everything you need to know, but a chance remains for one of the youngsters to become heroes against the club's bitter rivals.

Is Jack Wilshere worth a starting place?

Jack Wilshere was a surprise starter against Southampton in midweek, but his presence from the start against Spurs is not guaranteed. Aaron Ramsey and Mikel Arteta are likely to start, and if Ozil plays in the centre, roles become limited for the England international. After a handful of impressive appearances this season, Wilshere could be about to miss the game which he cares most passionately about.

Can Danny Welbeck deliver?

New signing Danny Welbeck will be expected to score against Spurs, and show he can deliver in big games. It is all very well netting against Aston Villa, but he drew a blank against Manchester City and Borussia Dortmund, and a failure to find the net against Spurs will be a mark against him. Not known as a prolific goalscorer, bagging against Tottenham would do wonders for his confidence.

Will Mesut Ozil step up?

If Welbeck thinks there is pressure on him to perform, it is nothing compared to Mesut Ozil. The German has brushed aside recent criticism after getting back to form against Aston Villa, but likewise, it will count for nothing if he turns in a woeful display against Spurs. Arsene Wenger must also do him a favour, and select him in a central role where he can dictate the play.

What is going on with Lukas Podolski?

Ozil may have questions to answer, but Lukas Podolski has played even more poorly when given opportunities this season. The German is now better known for posting photos of himself smiling on Twitter and Instagram than he is at scoring goals, and he was very poor against Southampton in midweek. Likely to be on the bench against Spurs, he needs to perform if given a chance.
