Holders Chelsea should have striker Demba Ba and defender Ryan Bertrand available for Sunday's FA Cup semifinal against Manchester City at Wembley.
.
Senegal international Ba, who was ineligible for Thursday's Europa League quarter-final at Rubin Kazan, suffered an ankle problem in last weekend's 2-1 Premier League victory over Sunderland and had to go off at halftime.
.
England fullback Bertrand, who has been deputising in the absence of the injured Ashley Cole, missed the trip to Russia due to illness.
.
Interim manager Rafael Benitez told a news conference that Ba and Bertrand took part in a light training session on Friday and he expected both players to be in his squad against City.
.
Cole and centre back Gary Cahill are again out with long-term injury problems.
.
Second-placed City beat Chelsea 2-0 in the Premier League in February but Benitez said he learned some valuable lessons from that defeat at the Etihad Stadium.
.
"We know what we did wrong when we played against them," said the Spaniard. "We will try to do these things well on Sunday.
.
"City are in a good position in the table and they did well against Manchester United the other day," added Benitez, referring to their 2-1 win over the Premier League leaders on Monday.
.
"We know it will be difficult but it is a semi-final of a massive competition."
.
A much-changed Chelsea side lost 3-2 against Rubin in Moscow and squeezed through 5-4 on aggregate to set up a Europa League semi-final against Swiss club Basel.
.
The European champions have had five fixtures in 13 days and Benitez was full of praise for the way his players had dealt with their gruelling schedule.
.
"The squad are doing really well," he said. "They are working very hard and I can change players and still keep a good level so I am really pleased with that.
.
"It is an advantage (for City), I don't know how much but we are trying to manage our squad and team selection and we have some players with fresh legs."
