MICHAEL Essien and John Mikel Obi have handed Chelsea a major fitness boost ahead of the new Premier League campaign.
The Blues duo missed out on the World Cup due to injury, but are on course for the big kick-off against West Brom on August 14, according to assistant boss Ray Wilkins .
He said: "There should be no problem whatsoever.
"John Obi is slightly in advance of Michael Essien but they are both working very well indeed.
"They have been working double sessions for the last week and we will get them really firing before the season starts."
