Striker Michy Batshuayi says he is feeling good after featuring twice for the Blues this week.
The Belgium international was on target as the Blues eased past Atus Ferlach by 8-0 in a friendly behind closed doors in Austria on Thursday.
And he admits it felt good to finally score his first goals for the club.
"I felt really good to play my first match in a Chelsea shirt," he told the club's official website.
"Beforehand the coach told me to use what I had learned in training and put it into practice during the game. It went well I think.
"I was just a little bit tired because it had only been two days after I had started preparations for the season, but I feel I am progressing bit by bit so it's no problem.
"I had a couple of chances on Wednesday and it was a bit of a shame not to score but that changed yesterday, so all good!"
