Chelsea midfielder Juan Mata has made no mention in his blog of allegations Mark Clattenburg used "inappropriate language" towards him in Sunday's acrimonious defeat to Manchester United.
Chelsea have made an official complaint that Mata and team-mate John Obi Mikel were the victims of comments from Clattenburg which are understood to have been interpreted as racist.
But the Spain international preferred to focus on the match itself at Stamford Bridge and look ahead to Wednesday's rematch at the same ground in the Capital One Cup.
"This time I'm writing to you from home, just arrived from Stamford Bridge, and obviously disappointed after our defeat," explained Mata on his grada360 blog on Sunday.
"It was a very important match for us, first vs second, and we were eager to win in order to open a gap at the top of the table. Yet we couldn't make it.
"The match started bad for us, conceding two goals in the early minutes (the first one very unlucky), but there was plenty of time to fight back. And we did it.
"Little by little, with the support of the crowd, we put more and more pressure on United and we managed to tie the game thanks to a very intense start in the second half.
"But soon afterwards, when the team's belief was higher, we had to play with nine men after Torres being unfairly sent off.
"Yet I prefer to be positive, we were very competitive against a great rival and we fought back with 0-2. Also we keep at the top of the table. It's still too early, but it's important to be up there.
"But football keeps going, there is no time to look back and this coming Wednesday we are again facing United, again at Stamford Bridge. The Capital One [Cup] this time. I hope we can win and forget today's defeat..."
