League season, Essien put in an excellent performance against Blackburn Rovers on 24 October 2009 and scored his first goal of the season with a swerving 35-yard shot on 52 minutes in a 5–0 victory at Stamford Bridge. He scored his first brace for Chelsea against Wolverhampton Wanderers with a header and a low shot from outside the box and came close to completing his first hat-trick for the club with a flurry of second-half shots, one of which was tipped onto the bar by Wolves goalkeeper Wayne Hennessey. Essien was injured on international duty during the 2010 African Nations Cup and missed the remainder of the English domestic season. On 4 June 2010, he signed a two-year extension to his existing contract which would have kept him at the club until 2015.
