Chelsea are convinced Harry Redknapp could become available at Tottenham.
The Daily Star Sunday says the Champions League holders have developed a sudden interest in Redknapp's future.
Sources say he's a possible stand-by contender if Stamford Bridge owner Roman Abramovich can't lure ex-Barcelona boss Pep Guardiola.
Redknapp, 65, still has a year left on his current deal, but would like a further two years at Spurs.
Sources claim chairman Daniel Levy wants to offer just 12 months because he is still frustrated the club threw away a ten-point lead over Arsenal, to miss out on automatic entry to the Champions League.
