Michael Essien believes Chelsea have the necessary quality in their squad to take three points away from Tottenham Hotspur at White Hart Lane. The two sides meet in a London derby on Sunday, with the Blues enduring a bout of bad form as they have registered only one victory in their last six games in all competitions. And with Spurs four points behind and threatening to undermine Carlo Ancelotti's charges' push to retain the Premier League title, the Ghana international believes that his side can bounce back from their barren run and return to winning ways at the Lane. "It is always very difficult to go to White Hart Lane," Essien said on the club's official website. "But we do have the players to do it. "We just have to play our game, concentrate on our football and come out onto the pitch with a winning spirit. The game plan is simple, go out there and get the three points. "We focus on the game, not the crowd. We know they will be singing and shouting and it's down to us to concentrate, play our football and try to win the game. We have to get ourselves back to winning ways." With Arsenal set to take on Manchester United on Monday, a victory over Spurs would temporarily send Chelsea to the top of the table. Source: goal.com
