Calum Chambers' transfer to Arsenal is now complete, after the defender confirmed his switch via his Twitter page.
The 19-year-old posted a photo of himself wearing an Arsenal shirt, expressing his delight at the deal going through.
Chambers is Arsenal's fourth signing of the summer, following Alexis Sanchez, Mathieu Debuchy, and David Ospina.
Wenger revealed last night it was the Southampton youngster's versatility which makes him such an attractive option:
"He can play at centre-back, right-back and central midfield. I hope he will give us competition for the players in these three positions."
