Tottenham defender Eric Dier says Dele Alli offers the team a fresh attacking edge.
"I thought he played really well. From the inside I can tell you he's been working really hard and trained really well," he said. "And against Sheffield United he put that on the pitch.
"Everyone knows his qualities, but I think he also has a lot of qualities which go unnoticed. The amount of second balls he wins, the amount he runs for the team and presses.
"He's always attached to the game, it's like he's on a string to the ball. He is always attached to the game in every moment and that's a great quality to have."
Dier added: "I think we have a lot of quality up front, even off the bench. We have a lot of quality in attack that no opposition would like to come up against. That includes Lucas Moura, Steven Bergwijn, Erik Lamela and the others as well.
"We have a lot of options and they are all options nobody would like to play against."
