What to do About Right-Back

As most Arsenal fans know: Bac is out of contract at the end of the season. There are reports that we are trying to tie him down with a new contract; but we all know how Wenger feels about players over 30, and how all players over 30 feel about 1 year contracts. He has recently had some injury problems and in an ideal world I would like Sagna to accept an extra year on his contract. Jenkinson can be brought in more and more and I would like to see him starting league matches by the end of next season. The exciting Hector Bellerin should be experienced enough to provide cover for Jenkinson by then and eventually compete for a starting position.

Sagna helping the youngsters

The problem is if the French fullback does not sign a new contract and Wenger has to start Jenkinson or buy somebody new. I don't believe that Jenkinson is good enough just yet, so who could Arsenal realistically buy?

Player Season Analysis: Per Mertesacker

When the big German came to Arsenal in 2011 I thought he would be like my younger brother: I would rather play squash with a pretty girl, but if she's not available my brother will do. He's slower than Tony Adams is now and already 28 years old, but Per Mertesacker had a good 2012/2013 season.

It didn't start particularly well, but his performances improved as the season went on and he formed an important partnership with Koscienly in the second half of the season. The centre-back scored 3 important league goals and received his third career red card. He played the third most games in the premier league behind Cazorla and Arteta.
