DEFENDER Gary Cahill put a halt to Chelsea's celebrations this morning by reminding his team-mates they have achieved nothing yet despite their impressive 1-0 win over Barcelona in London last night.
Didier Drogba scored deep into first-half injury-time to give the Blues the advantage in their Champions League semi-final.
The Londoners rode their luck at times, and Barca enjoyed an incredible 72pc of possession, but the fact that they suppressed the magical talents of Lionel Messi, Xavi and Andres Iniesta has given the club a belief that they can upset the odds in Tuesday's second leg at the Nou Camp.
Pep Guardiola's side have a mightily impressive home record - they have not lost there since September 2010 - and Cahill has warned Chelsea they still have a huge mountain to climb before they can reach what would be only their second Champions League final.
"It was a fantastic result but it's only half-time," Cahill said. "I thought as a team we were well organised.
"The gaffer gave us a plan before the game and we stuck to it. It worked really well, but it's half-time and it's going to be really hard over there. It's a good start for us."
Interim boss Roberto Di Matteo paid tribute to Chelsea's "old guard", insisting they had answered their critics in the victory.
"In the past, a lot of the public opinion has been that these boys are over the line, too old to play two games, and to play at this level," he said.
"It wasn't just Drogba. There were other players on the pitch that you regard as the old guard who can't play two games. But they gave an answer on the pitch."
The Italian was keen to acknowledge that every player had contributed to the performance.
"I talk about the team," he said. "You talk about them as the old guard. We have a team, a good team spirit, a good team ethic. Young and old stay together in this team and fight for the same target."
Di Matteo denied that Barca's domination meant they deserved to win.
"When you score a goal and you win the game, you deserve to win it," he argued. "Certainly, they have had more possession and a few more attempts on target, but they always have that. You need to be clinical to take your chances when you play against them."
Despite having the lead, and not having conceded an away goal, Di Matteo said that the tie was still even.
"I don't think it makes us favourites," he said. "It's 50-50 to go through to the final. You know what to expect when you play at Nou Camp.
"It'll be very, very difficult and we still have to believe that we might be able to score a goal there as well. It'll be a tough game. It is for any team going to Barcelona. We'll have to give our best again.
"I am very pleased with this result but it is only half-time."
