Kai Havertz insists he won't use any excuses for his failure to make an impact for Chelsea.
The German missed two of Chelsea's best chances in the goalless draw with Leeds United on Sunday.
"Corona is now over, I feel good," Havertz told The Mirror. "I had a little injury in the past few weeks, but it's now time to play good.
"I have to improve my game. It's not been easy for me, but there are no excuses.
"I just have to keep on working and hopefully there will be a big turnaround soon, but I will give it my best.
"For me it has been difficult to change everything. It's hard for me, but I'm six months here and getting used to the place, to the country.
"I hope that I will see my family soon. It's tough for me, I've always loved spending time with them.
"It has not been the right time to spend some time with them. But it's not only me, there are thousands of other people in an even worse situation than me.
"It isn't an excuse for me. I will give my best."
On the team's failure to score at Elland Road, Havertz added: "We don't score enough goals. We get good chances, but we're not clinical enough in front of the goal.
"We had good chances against Leeds, I had two chances myself.
"We have to keep working hard and make it better next time."
