It's fairly common knowledge that North London rivals Arsenal and Tottenham need to add defensive options in the January transfer window.
Arsenal have suffered with injuries again this season, which was resulted in a number of different centre back partnerships, which have included Calum Chambers, Mathieu Debuchy and Nacho Monreal - none of which are natural centre backs.
Meanwhile, Tottenham boss Mauricio Pochettino has tinkered with the centre of his defence, playing Younes Kaboul and Vlad Chiriches before settling on Federico Fazio and Jan Vertonghen, though rumours continue to link the latter with a move away in January.
A number of different defenders have been linked with both clubs, including Tyrone Mings and Benedikt Howedes for Arsenal, whilst Hector Moreno and Virgil van Dijk have been touted as targets for Tottenham.
Now though, they could be poised for an intense transfer battle over Monaco's Aymen Abdennour. The 25-year-old has established himself as one of the top defenders in Ligue 1 during spells with Toulouse and now Monaco - and his agent says both Tottenham and Arsenal want to sign him.
"It's true. Tottenham follows his recent matches," said Abdelkader Jilani. "They are interested. They contacted us to tell us about their interest in Aymen. We are this stage. I do not think it will be this winter but for next summer. Arsenal also keeps an eye on him."
So it seems both sides may need to wait for any bid for Abdennour, but Arsenal will get to see him first hand when they play Monaco in the Champions League in February and March - and if he impresses, Wenger could well look to lure him to the red half of North London.
An athletic defender with size, speed, strength and aerial ability, Abdennour is a left footed defender who would be a great replacement for Vertonghen should the Belgian leave Tottenham, whilst with question marks over Per Mertesacker at Arsenal, he could also slot into the Gunners defence.
