Chelsea have received a double fitness boost with midfield duo Frank Lampard and John Obi Mikel back in training after injury lay-offs.

Talismanic midfielder Lampard has missed the Blues' last three matches with a calf injury, while Mikel has been on the sidelines for seven weeks with a hamstring problem.

Both men trained at Chelsea's Cobham base on Wednesday with Lampard pushing for a recall ahead of Saturday's Premier League trip to Everton.

The match may come too soon for Mikel, however, although his return to training comes as a boost with fellow midfielder Ramires currently ruled out with a knee injury.

Full-back Ashley Cole has served a suspension, but captain John Terry (knee) remains a doubt.

Chelsea occupy fourth place in the Premier League but defeat at Goodison Park, combined with wins for Newcastle and Arsenal, could see Andre Villas-Boas' men fall to sixth.

Owner Roman Abramovich was also understood to have again attended training today - this third recent visit to Cobham.

The club though have already denied any suggestion that manager Andre Villas-Boas was coming under increased scrutiny from the billionaire owner.

Chelsea are aiming to fall in line with UEFA's new financial fair play rules and recently announced a total loss of £67.7million for the financial year ending June 30, 2011

Accounts have now been made available at Companies House, and show revenue rising by 8%, with a 2.6% fall in wages.

However, the next six months will see the "amortisation charge" - which is how transfers spending is recognised across the life of a player's contract - go up to take into account the deal for Luiz and Fernando Torres, signed for £50m in the same January window last year.

The club's overall operating loss had reduced from a figure of £70.9m to £67.7million.

UEFA's new rules at curbing football's finances are set to kick in from 2013/2014.

Clubs hoping to take part in the Champions or Europa Leagues must balance their football-related expenditure over a three-year period, but will initially be allowed to make a loss of £37.5m (45m Euros), falling to £25m (30m Euros) from 2015/16.
