Diego
Costa took part in training ahead of Chelsea's Champions League last-16
clash with Paris Saint-Germain on Wednesday.
Costa missed Saturday's 1-1 draw with Stoke with a minor tendon problem but
is set to return to the squad after showing no signs of injury in training.
However, as expected, captain John Terry looks likely to miss the second leg
at Stamford Bridge, after he failed to take part in training on Monday.
Terry has missed Chelsea's last five matches after suffering a hamstring
injury during Chelsea's 5-1 win over Newcastle in February.
Chelsea interim boss Guus Hiddink had been optimistic about Terry's chances
of featuring against the French champions, but conceded on Monday that the
game could come too early for the 35-year-old.
Forward Pedro was another player to miss the match with Stoke at the weekend
after being ruled out with a hamstring problem.
It had earlier been reported the former Barcelona forward had been taking
part in extra training to prove his fitness and, like Costa, took a full
part in Monday's session and should be available for Hiddink's side.
Meanwhile, Radamel Falcao also trained with the squad having not featured
since Chelsea's 3-1 defeat to Liverpool on October 31 with a thigh injury.
Hiddink said in January that the striker's problem was "very serious," and
refused to set a timeframe for his return.
