Tottenham midfielder Dele Alli believes victory at Barcelona would be among their best results yet.

Mauricio Pochettino’s Spurs go to the Nou Camp in the Champions League on Tuesday knowing victory would seal a spot in the knockout stages.

They are level on seven points with Inter Milan, who host PSV Eindhoven, in Group B.

Alli scored his 50th Tottenham goal in Saturday’s 2-0 win at Leicester and, after Spurs failed to win their opening three group games, the midfielder feels victory in Spain would be one of the squad’s greatest successes.

He said: “It would definitely be up there. They are one of the best teams in the world, they’ve got some great players and as a kid you dream about playing at the Nou Camp and we’re going to go there and give it our best shot.

“I’ve had a bit of a cold but it’s not too bad.

“A cold won’t keep me out. We’re ready. It’s going to be another difficult game but they’re the games you want to be a part of, playing one of the best teams in the world and some of the world’s greatest players.

“You want to be challenging yourself and we’re going there with the mentality that we can win and we have to believe.

“It’s going to be difficult but we have to go there and give it our best.”

Alli doubled Tottenham’s lead on Saturday after Son Heung-min’s classy first-half opener.

Victory lifted Spurs to third in the Premier League and boss Pochettino insisted they can win in Barcelona.

He said: “We have a chance. Yes, I believe. I think we believe, that’s the most important thing, and then what happens happens, we are going to enjoy the game.

“Of course (I thought we were still in it), then we won against PSV and Inter, two victories, and then the third is possible of course.

“It’s always an exciting place, they’re one of the best teams in Europe and I know it’s amazing, very exciting to play against them.

“But at the same time it’s going to be tough to play there, we’re going to play one of the best teams in Europe and the only way that we can be happy will be to win the game, and that will be tough.”

Without the injured Jamie Vardy, missing a second game with a groin injury, Leicester were toothless.

Kelechi Iheanacho was jeered when he was substituted but boss Claude Puel said he was not thinking about striking reinforcements next month.

He said: “It’s always difficult, the transfer window. My focus is to prepare for Crystal Palace because we need points, we need to go up in the table.

“It will be a tough game but it’s important after the loss to keep a good mentality and a clinical edge.”
