Chelsea defender Gary Cahill felt there were decisive moments and decisions that did not go in his side's favour as they slumped to a 2-1 defeat at the hands of West Ham on Saturday.
The Blues' torrid start to the Premier League campaign continued as striker Andy Carroll headed home in the second half to fire the Hammers to victory.
This after Nemanja Matic saw red in the closing stages of the first half before Cahill converted in the early stages of the second period to restore parity.
"We reacted really well in the second half but we got nothing for it," Cahill told his club's official website.
"We worked as hard as we could. It is always tough with 10 against 11 in the Premier League but nevertheless we worked really hard and had the majority of the play. We got done with a sucker punch.
"You're left scratching your head sometimes. In the first half Cesc's goal could have been given, the way things are going it wasn't and we had the goal that was nearly over the line. It is those fine margins. That sums up the way we're going.
"And then we've got the sending off. We thought the referee had carried on. We were all getting organised in the box and, I'm not sure what's happened, maybe the linesman called it back.
"There's a bit of frustration really. It could have been 1-1 and still 11 against 11 and then it's a totally different game."
He added: "Not many words are being said at the moment. The mood in the dressing room is not great like you'd imagine when you lose games.
"The lads are devastated. I'm sure we'll reflect in the next day or so.
"We've not had the rub of the green but we're not feeling sorry for ourselves. We have to work even harder to try to turn this round because it's a tough time at the moment."
Chelsea manager Jose Mourinho was also given his marching orders during the Premier League clash and is now waiting on word from the league's governing body regarding a potential lengthy touchline ban.
