Roberto Di Matteo will give Victor Moses his first start for Chelsea against Wolves in the League Cup tonight, having revealed that he wanted to sign the 21-year-old "years ago".
"He's an exciting player and I tried very hard to sign him, not just this year but previously as well, years ago," said the Italian, who had spells as boss at West Bromwich Albion and MK Dons before moving to Stamford Bridge.
Marko Marin, Lucas Piazon and Cesar Azpilicueta could also make their first appearances for Chelsea, who will face either Monterrey of Mexico or the winners of the Asian Champions League in the semi-finals of the Club World Cup following the draw for the tournament yesterday.
Di Matteo's side received a bye in the first round of the competition, which is to be held in Japan from December 6-16, when goal-line technology will be tested for the first time.
Manchester City manager Roberto Mancini has indicated he will make wholesale changes against Aston Villa, but he will still field a team boasting plenty of firepower, with Carlos Tevez and Mario Balotelli both likely to play.
That could spell bad news for Villa, who lost 4-1 to Southampton last Saturday.
Leeds manager Neil Warnock insists his players will go into the match unburdened by expectations.
"There's no pressure on us in this competition because everybody will expect Everton to win, so we can go out and enjoy it," Warnock said.
"Everton are very high on my list of potential favourites to win this competition.
"Teams like Everton and Newcastle have got a great chance of winning it this year, so they will have a very strong side out. But we can give most Premier League teams a run for their money."
The Swans head to the Broadfield Stadium on the back of consecutive Premier League defeats to Aston Villa and Everton.
