Tottenham fullback Danny Rose is eyeing a move to Germany.
He is likely to end his 13-year association with Tottenham this month.
His Spurs contract expires in June and could be cancelled by mutual consent.
Allardyce is desperate to bring in Rose.
But with money tight at the Hawthorns he might have to off-load Kieran Gibbs first.
Spanish and German top-flight clubs have also shown interest in Rose, 30.
