Five players who fit Wenger's latest Arsenal transfer wish - Carvalho ideal?

Javi Martinez Appearing For Spain Under 21s

With both centre back and defensive midfield positions needing strengthening, reports suggest that Arsenal could sign one player to play both positions.

The Gunners have already moved to sign four new players, with goalkeeper David Ospina and right backs Calum Chambers and Mathieu Debuchy joining Chilean international forward Alexis Sanchez at the Emirates Stadium. However, with a title challenge expected having won the FA Cup final against Hull City in May, Arsenal still need to add more bodies.

A particular area of concern has been in holding midfield, where Arsenal have lacked the combination of grit, determination and technical ability. Fans had hoped for the signing of Real Madrid star Sami Khedira, but Arsene Wenger confirmed on Thursday that the German isn't of interest to him.

Now, with centre back Thomas Vermaelen reportedly on his way to Barcelona in a £15m deal, Gunners boss Wenger is reportedly looking to sign a player who can play both centre back and defensive midfield, rather than buying two players - so here are five suggestions for Arsenal, with less than a month to go until the transfer deadline.

William Carvalho, Sporting Lisbon

The Portuguese youngster impressed for Sporting Lisbon last season and with Portugal at the World Cup. It's believed that Sporting are willing to sell the £30m-rated Carvalho, and Arsenal are near the front of the queue - his versatility to play centre back and in midfield could be why.

Javi Martinez, Bayern Munich

This one may be the most costly of all the suggestions, but rumours this summer did hint that Martinez could look to leave Pep Guardiola's side this summer - and he's the perfect candidate for what Wenger wants.

Alex Song, Barcelona

Barca still want to get rid of the Cameroon international this summer, and whilst his performances at centre back have been inconsistent, a return to the Emirates could work for all parties.

Lorik Cana, Lazio

Wenger was reportedly a fan of the Albanian during his time at Marseille, and with Lazio looking to bring in younger defenders, Cana could be back in play for Arsenal due to his vast experience in both required positions.

Loic Perrin, Saint-Etienne

A highly rated versatile player after a superb season in Ligue 1, Perrin has experience in a number of positions, including full back, centre back and holding midfield. This would be an under-the-radar signing from Wenger, but his knowledge of French football could be a factor here.
