Jeremy Toulalan is adamant that Monaco can still qualify for the group stage of the Champions League - provided they cut out the defensive mistakes which characterised their 3-1 defeat in Valencia on Wednesday.
The Ligue 1 outfit found themselves a goal down after just four minutes of play at Mestalla, with Rodrigo opening the scoring for the hosts, but the visitors replied through Mario Pasalic just after the interval.
However, Monaco then allowed Dani Parejo to put Valencia back in front and the conceded an 86th-minute goal to Sofiane Feghouli that completely changed the complexion of the two-legged tie.
Toulalan admitted afterwards that last season's quarter-finalists now face an uphill task at the Stade Louis II next Tuesday - but the Monaco captain has not given up hope of turning the tie around.
"We committed defensive mistakes and we paid heavily for them," he told beIN Sports. "It's all a shame because we had chances to score and we did not.
"We could have got a draw but there is still much to play for. We saw that we can create chances, so anything is possible.
"It will be tough but if we start well at home and score the first goal, everything is still open to us."
