Last meeting: Tottenham won at Old Trafford for the first time for 23 years back in September. A Jan Vertonghen shot eventually went down as a Jonny Evans own goal and Gareth Bale doubled the lead with an individual strike. Clint Dempsey restored the two-goal margin seconds after Nani pulled one back and, despite a Shinji Kagawa effort, the visitors held out for a famous success.
Did you know? John O'Shea went in goal during the 4-0 victory at White Hart Lane in 2007 when Edwin van der Sar broke his nose. The Irish defender not only kept a clean sheet in the closing stages but also made a decent save to frustrate fellow countryman Robbie Keane.
Opposition boss: Andre Villas-Boas arrived in England with a big reputation after working wonders at Porto and earning a tag of the 'new Jose Mourinho'. Clearly a shrewd tactician, he was given the brief of managing Chelsea's transition but it proved to be a difficult job with the old guard later proving they were still capable of success, culminating in the Champions League triumph in Munich. Villas-Boas had left months earlier, with Roberto Di Matteo stepping into the breach, and the young boss was snapped up by Spurs in the summer following Harry Redknapp's exit.
Star man: Gareth Bale will be a major threat after shining in the match at Old Trafford. The Welsh winger has been a key figure all season and drifts in centrally to offer even more danger to defences. A United target in his Southampton days, he is likely to give Rafael a testing afternoon if the Brazilian plays. However, the South American full-back has dealt impressively with Bale in the past.
