Upton Park legend Redknapp, below, who played for the club and managed them for seven years up to 2001, was last night installed as the bookies’ favourite to return, with Allardyce effectively given a few weeks to save his job. Allardyce has been publicly backed by Hammers owners David Sullivan and David Gold and given the go-ahead to strengthen his squad. Wolves defender Roger Johnson has signed on loan – and will go straight into the line-up for tomorrow’s Capital One Cup semi-final first leg at Manchester City – with Ivory Coast striker Lacina Traore due to complete a similar deal from Monaco. The Daily Express understands that Redknapp will be the chief contender if Allardyce fails to survive. The 66-year-old is becoming disillusioned with QPR and would welcome a return to east London.
