Antonio Conte says managing Tottenham is his "biggest challenge" to date.
The Italian, who took over as Spurs boss at the start of November, said his new side's level was "not high" after they were embarrassed by NS Mura in the Europa Conference League last week.
Spurs are seventh in the Premier League having won just one of their past three games, and play Brentford on Thursday.
"Biggest challenge, yes. But as I said in Mura, I'm not scared about this," said Conte.
"I have a lot of enthusiasm. When I arrive here, I enjoy the situation.
