Chelsea manager Guus Hiddink says striker Diego Costa is bitterly disappointed after seeing red in the FA Cup defeat against Everton last week.
The Spaniard will miss games against West Ham United and Aston Villa but his punishment could increase if a commission decides so next week.
The 27-year-old was also omitted from Spain's squad for friendlies against Italy and Romania.
"Of course he's [Diego Costa is] not happy and he will see if he gets another game as well," Hiddink said.
"'We'll see if it goes to a third game, yes or no. He desperately likes to play and he accepts he's suspended, but he's not happy.
"[Gareth] Barry made a very good statement by saying what happened or what didn't happen in this case. Maybe there was a bit of searching for Diego in terms of where they could get him.
"We talked many times about him playing on the edge and his reactions. We were, and still are, happy with his performances but I told you I could never give a guarantee he wouldn't be provoked. He knows he has to control himself, that's why we had a conversation.
"It's a matter of temperament and character. If he reduces what he did more frequently in the past then we are progressing.
"I expect a tough match [today] because they are doing very well at home and away.
"They are a courageous team who are fast on the counter attack. They have skillful players, they are a nice team to watch.
"They are in the mood in fifth position, not just dreaming but maybe making fourth place come true. They've shown they can play and they have players who can be decisive at any minute."
