Wembley is gearing up for its second FA Cup semi-final and it's another derby. After Liverpool beat Everton yesterday, it's now the turn of north London against west London. But the game will also be a battle between two managers.
Harry Redknapp remains the main contender for the England job. As luck would have it, Tottenham have been given the home dressing room. Redknapp will literally try the England manager's chair for size when he sits in the dugout later.
Redknapp will be hoping to impress FA bosses with a good performance. After a strong start to the season, Tottenham have struggled. Since Redknapp became the favourite to take over at England, Spurs have won just two from nine Premier League games.
As for Chelsea, they have a temporary man in charge. Caretaker manager Roberto Di Matteo seems to have brought out the best in this ageing side. He's slowly becoming a serious contender to take over the job permanently. The Blues have lost just once in 11 games since taking over from sacked Andre Villas-Boas.
The main worry for Chelsea is that they have another semi-final just 72 hours after this fixture. That's against arguably the best side in the world - Barcelona. The Champions League remains the trophy that has so far eluded the Blues and their billionaire owner Roman Abramovich.
But Chelsea somehow manage to do quite well in the FA Cup. They've won it three times in the last six years. As for Tottenham, they last won the FA Cup back in 1991. Lots to play for, and lots at stake for both teams and their managers.
