Kalou says winning the Champions League is possible as Chelsea await Benfica
12:17 GMT, 31 March 2012
Salomon Kalou insists Chelsea should fear themselves more than Benfica when they meet in the second leg of their Champions League quarter-final.
The rivals clash at Stamford Bridge on Wednesday with the Blues in the driving seat after leaving the Estadio da Luz with a 1-0 victory last week.
A semi-final against Barcelona or Inter Milan awaits on April 18 should they dispose of Benfica, but Kalou is wary of complacency.
'I think our worst enemy can be ourselves, thinking that we have done the most difficult part,' he said.
Winner: Kalou scores against Benfica
'We have to keep going, working hard. We have to prepare and try to score early and secure the victory at home.
'It's not finished yet. Benfica are a good team and we have to respect them.
'We have to play 100 per cent in the second leg if we want to go through to the semi-final.'
Chelsea host Benfica with a precious away goal in the bank, meaning any score draw at Stamford Bridge would see them progress.
'We know that scoring in the away game is always important, and we haven't conceded,' Kalou said.
'It's still going to be a difficult game because Benfica are a great team, as they showed against Manchester United before, so we have to respect them.'
focus: Chelsea are determined to reach the semi-finals
Five points adrift of the Barclays Premier League's top four, winning the Champions League could yet be Chelsea's only avenue of qualifying for the competition next season.
Such a notion seemed far fetched as recently as eight games ago when the team was creaking under the guidance of Villa-Boas, but the arrival of Di Matteo has brought fresh hope.
With Di Matteo at the helm, they have won all four cup games, although one win in three Premier League matches is less impressive.
'Winning the Champions League is possible, everything's possible,' Kalou said.
'Given the team that we have, we know we can win against any club. We have to work hard as a team and continue to improve in every game.'
