Southampton defender Calum Chambers is the newest addition to the Arsenal team after completing a £16million move to the emirates. Chambers can play in the right back, Centre back and midfield positions. The 19year old who spent two years at Southampton Academy will be Arsene Wenger's fourth major signing of the transfer window after previously acquiring the services of Alexis Sanchez, Mathieu Debuchy and just recently Colombian international and Nice goalkeeper David Ospina. Chambers becomes another Southampton young player to move to Arsenal following in the footsteps of Theo Walcott and Alex Oxlade-chamberlain and he becomes the latest player to take part in Southampton's exodus this summer as first team players like Rickie Lambert, Adam Lallana, Luke Shaw have already left the club while the likes of Dejan Lovren and Morgan Schneiderlin may follow suite with the transfer of Lovren to liverpool in the closing stages and Schneiderlin to Arsenal a possibility. This obviously outlines Arsene Wenger's ambition this season and now Arsenal can truly maintain a sustained challenge for the Premier league title.
