Chelsea and Tottenham put on a classic as they battled for a place in the FA Cup final at Wembley on Saturday.Ultimately, it was the league leaders Chelsea who emerged victorious with a 4-2 win and they will face the winner of Manchester City and Arsenal tomorrow.Willian grabbed a dead ball brace in the first half with a clever Harry Kane header sandwiched in between to make it 2-1 at the break.Christian Eriksen provided a wonder ball for Dele Alli to level the scores, but the introductions of Eden Hazard and Diego Costa in the 61st minute changed the complexion of the game.Just 14 minutes later and Hazard was let unmarked on the edge of the box from a corner and the Belgian duly made Spurs pay.But, plenty of Spurs fans believe it could have been avoided and are pointing the finger firmly at Eric Dier.The England international, who has been linked with a summer move to Manchester United, looks like he could have blocked Hazard's effort on its way through, but he failed to stick out a leg.As you can see from the video, he only had an instant to make a decision, but it was clearly the wrong one that he made.Tottenham fans slated the holding midfielder on Twitter and believe he should have been absolutely hurling himself at the effort.

Hazard's impact delighted the Chelsea faithful and he also went to assist Nemanja Matic for the Blues' fourth and best goal of the day - it really was special.

However, Hazard revealed after the game that he was well aware he would be starting on the bench for the game after boss Antonio Conte spoke to him yesterday.

"It's always good to win this kind of game. It will be my first FA Cup final with Chelsea and I hope to win this competition.

"The manager told me yesterday [about being on the bench]. When you play football you want to play every game but he made a good choice. Willian played a good game and scored twice."

Chelsea are still four points clear of Spurs at the top of the Premier League and looking at their run in, you would be brave to bet against them lifting the trophy now.
