#5 Mikel Essien
Essien had to be on this list. Known as The Bison, Essien in his prime was unstoppable. He was the perfect box to box midfielder. While he preferred to play in midfield, he could also slot in at the back. At Real Madrid, he even played in the right-back position.
Apart from his work rate, Essien also had great vision and passing ability. Over his time with Chelsea, he scored some stunning goals. His most famous goals are his volley against Barcelona and his long-range strike against Arsenal.
Essien was a great player but always put his team first. He sacrificed his position and often played injured. For that reason and more every true Chelsea fan misses The Bison.
While there a lot of videos of his goals, the video I love about Essien is Jose Mourinho talking about him.
