Michael Essien believes that training hard, coupled with a good team spirit, will see Chelsea turn the corner and regain their Premier League dominance.The Blues have had a difficult time in terms of their recent form, as they have won only one of their last five games in the Premier League. This has caused Carlo Ancelotti's charges to lose the top spot to an in-form Manchester United side, which currently have a two-point lead over the Londoners.However, the Ghana international, who will return from suspension this weekend, believes that his side will turn a new leaf."My ban is over so I am looking forward to getting back on the pitch and doing what I do best," Essien told the club's official website."The snow is starting to get heavier and no doubt the snowball fights will start soon when training is over but it’s always serious training first."We are working hard in training to turn things round after our recent sticky patch and I believe the togetherness, ability and spirit in the camp will see us through."Source: Goal.com
