Chelsea manager Thomas Tuchel believes his side is getting better by the day following a recent run that has seen them lose just once in the last 13 games.
The Blues were among the Premier League title favourites early in the season but faded after leading the opening two months.
They are currently third on the table, 11 points off league leaders Manchester City but with a match at hand.
“In those earlier games I think we lacked luck and in the last 12 matches we had not always super-impressive performances,” Tuchel says.
“We were also sometimes lucky to escape then. Just one example is the away game at Crystal Palace which was not the very best game from us and could have been easily a draw and we scored in the very last minute.
“So it’s sometimes like this. We struggled in the period where the gap opened up between Liverpool and City and us. Unfortunately, we struggled with long-term injuries and coronavirus.
“There was the time when we arrived with 14 players at Wolverhampton, there was a time when coronavirus hit us because players had to isolate for 10 to 12 days, this was the rule, even if they had no symptoms. So we struggled from that but the attitude was always on a very high level,”
Chelsea will face Brentford in their next Premier League match after the international break.
