Spurs can win the Champions League...

"Step by step. The most important thing is tomorrow," he said.
Spurs took Dortmund apart in the first leg but face a tougher test in the quarter-finals.
"In competitions like the Champions League or Europa League or domestic cups in England, Carabao or FA Cup, you need not only to win games you need to be more than lucky sometimes to arrive to play the final.
