Tottenham midfielder Dele Alli believes they are a match for anyone in the Champions League, despite losing their opening game in the competition to Monaco.
Spurs conceded twice in the opening 31 minutes at Wembley and even though Toby Alderweireld pulled one back before half-time, the Principality outfit held on for the win.
The north Londoners expect results to improve in the coming weeks and Alli says they are brimming with confidence.
"We fancy ourselves against anyone," the playmaker said. "We're a confident side and we expect to win games, no matter who is in front of us.
"We let ourselves down in the first half against Monaco. We need to make sure we keep improving and win the next game. We usually bounce back well from a defeat and it's important we pick ourselves up on Sunday against Sunderland.
"We have to make sure we learn from Monaco and take it into the next games. We've got some fantastic fans here at Tottenham and it's a great club to play for and the whole team are sorry we didn't win.
"But it's important we pick ourselves up and keep learning from these experiences and make sure we win the next game. And hopefully we can get a win as well."
Their next assignment in the group stages is a tough trip to Russia to face CSKA Moscow.
