Chelsea need to bounce back from dropping points in consecutive Premier League games when they face Tottenham Hotspur on Sunday for a fourth time this season.
The Blues dropped vital points in what is a race for the top four with a loss against Manchester City all but ending their title hopes and a draw against Brighton brought their top four position into question as well.
"We won twice against Tottenham in between [in the Carabao Cup] and had some other tough fixtures. I can't even tell you the last seven games in the league so I have no answer," Tuchel said when asked about recent dip in form.
