Player: Matty Derbyshire

Club: Notts Forest

Possible move to: Portland Timbers

Time left on deal: 18 months

Chance of moving: Four stars

Player: Wilfried Zaha

Club: Crystal Palace

Possible move to: Manchester United

Time left on deal: Four-and-a-half years

Player: Jonas Olsson

Club: West Brom

Possible move to: QPR

Time left on deal: Three-and-a-half years

The story: Harry Redknapp desperately needs a commanding centre half with Premier League experience and Olsson is having one of the best seasons of his career. A possible sale clause of £4million in the summer has alerted Redknapp that West Brom might be willing to do business now.

Club: Wigan

Possible move to: Everton

Time left on deal: Three-and-a-half years

Player: Philippe Coutinho

Club: Inter Milan

Possible move to: Aston Villa

Time left on deal: Two-and-half years
