Andre Villas-Boas was left to rue missed chances from his side in Genk as Chelsea were forced to settle for a Champions League point in Belgium.
Less than two weeks after Mario Been's side were handed a 5-0 thrashing at Stamford Bridge, the hosts earned their second point in Group E and had chances of their own to win the match at the Cristal Arena following Jelle Vossen's 60th minute equaliser.
Ramires had put the visitors in-front on 26 minutes, but David Luiz's penalty miss in the later stages of the first-half proved crucial as Villas-Boas was left to contemplate another disappointing result after Saturday's 5-3 loss to Arsenal.
"It's not a bad result away from home, but we expected to win. I wouldn't say we lost control. We were quite organised in the first-half and in the second-half I think we shouldn't confuse losing control of the game with emotions coming from the stadium," said the former Porto boss.
"We created enough opportunities again to try to win the game but it's not happening for us in terms of efficiency. We got a penalty, hit the post and got in front of the goalkeeper a couple of times, so [it is] efficiency at the moment.
"It's things we need to focus on because it can put us clear in terms of the result and we can move clear for the second half with 2-0. When you don't the game is always open and there for you to be threatened. Genk made the most of a couple of opportunities they had."
The draw is the latest set-back to the Blues, who lost the west London derby to QPR last Sunday, survived a Carling Cup scare against Everton after extra-time and were then humbled by the Gunners at home.
However, they remain top of the pile ahead of both Bayer Leverkusen and Valencia in the table, and Villas-Boas is confident positive results are just around the corner.
"When you get a bad run of results you have to get a win straight away to take you out of that run. You play difficult games, and at the moment we are chasing hard this win, but we haven't found it today," he added.
"Our reflection must be on what we did in the game, was it enough to win? I think it was but we couldn't find the back of the net and that made the difference. It's back to back games without a win but it is a draw away from home in the Champions League. We still lead the group."
