Mauricio Pochettino expects to be at Southampton next season and is looking forward to working with chairman Ralph Krueger.
Loan pair Sam Hutchinson and Leon Best have extended their deals at Sheffield Wednesday.
Queens Park Rangers goalkeeper Julio Cesar is reluctant to be drawn on speculation linking him with a summer return to Italy.
The Brazil international left Inter Milan for Loftus Road last summer as part of a major rebuilding project at QPR.
He was one of a number of high-profile recruits brought in by the Premier League club, as they attempted to piece together a competitive squad.
Cesar has impressed during his time in England, but too many of his team-mates have disappointed during what has been a hugely woeful campaign.
With QPR still sweating on their top-flight status, speculation has surfaced regarding the future of their top assets.
It is not expected that Cesar would be willing to turn out in the Championship, should QPR suffer relegation, and a move to AC Milan has been widely touted.
The Samba shot-stopper is, however, keen to focus all of his efforts on a late survival bid.
Cesar said: "My priority is to help QPR avoid relegation."
