Olympiakos coach Michel was left to rue his side's missed chances as the Greek champions crashed out of the Champions League round of 16 to Manchester United on Wednesday.
The visitors arrived at Old Trafford with a two-goal lead from the first leg but were sunk by a Robin van Persie hat-trick as United roared back to win 3-0 and book their place in the quarter-finals.
But Michel believes that it could have been a different story had his side converted their opportunities, with David de Gea forced into a handful of fine saves for the home side.
"We had our chances but failed to convert them," he told Uefa's official website, "and teams who do not make the most of their scoring opportunities at this level end up paying for it.
"I would like to congratulate my players on their effort. Looking at the result, one might think that it was a one-way match but that was not the case.
"Football is played in both areas and we committed errors at both ends."
