Football: Chelsea go into PSG tie with spirits boosted after lifting League Cup, says Cahill

LONDON (Reuters) - Chelsea are brimming with confidence and, fortified by a seven-day break, go into Wednesday's Champions League last-16 return match as favourites to knock Paris St Germain out for the second season in a row.

Defender Gary Cahill says "there's a great buzz" around Stamford Bridge after the Londoners followed their 2-0 League Cup final victory over Tottenham Hotspur on March 1 by winning 1-0 at West Ham United in the Premier League three days later.

Treble-chasing Chelsea, who are five points clear at the top of the Premier League, have not played since their Upton Park triumph and, according to Cahill, the Wembley win over Spurs has lifted the squad's self-belief.

"The Cup final was huge in terms of the atmosphere around the club and the dressing room," he told the club's website.

"We were desperate as a squad to win that game. It's the first time this group, a newish group formed at the start of last season and before this season, has reached the end of a competition together.

"But they are gone, all that is on our minds now is the PSG game."

Last month's first leg in Paris ended in a 1-1 draw and visiting coach Laurent Blanc wants his attack to be more ruthless than they were during Saturday's 4-1 victory over struggling RC Lens in Ligue 1.

PSG will be without injured forward Lucas but fellow Brazilian David Luiz returns to Chelsea for the first time since moving to Paris in the close season.
