Check out all the latest Arsenal news and transfer gossip from today.
Calum Chambers has only been an Arsenal player for a matter of hours, but he's already rubbing one of his new team-mates up the wrong way after Alex Oxlade-Chamberlain revealed plans to launch a legal battle over the protection of his nickname. (Metro)
The Gunners midfielder known as 'Chambo' took to Twitter to welcome his fellow Southampton scholar to the Emirates Stadium, before jokingly announcing his intention to sue him in a bid to try and lose the moniker.
"Although I'm ready to go to court regarding the whole nickname situation, really happy to see Calum Chambers at Arsenal. Big future! #chambo," he tweeted.
The 19-year-old defender formally completed his Arsenal transfer on Monday and immediately flew out with Arsene Wenger's first-team squad to a pre-season training camp in Austria.
Chambers is the fifth Southampton player to depart St Mary's this summer, and follows in the footsteps of Oxlade-Chamberlain and Theo Walcott by swapping the south coast for north London.
Let's hope that the light-hearted dispute is ironed out before the end of the tour, so that the players can focus fully on preparations for the new season.
