Arsenal has signed Calum Chambers from Southampton in a £16 million transfer.
Chambers will initially provide cover for another signing, the £10m Mathieu Debuchy, at right-back and will also be utilized at center-half.
Arsène Wenger believes the 19-year-old Chambers will eventually move to central midfield.
While Chambers would expect to feature for Arsenal in domestic cup competitions, he has been told he will play at least 20 senior matches this season, with Arsenal also set to compete in the Champions League.
