The Welsh winger, 23, plans to destroy them again as Tottenham look to catch their Europa League rivals on the break.
He said: “The good thing is that they are going to have to come at us now as they’re behind in the tie.
“Hopefully that will leave space in behind. It is going to be a difficult game as they made it difficult for us in patches.
“But it was great to get the goals in the first leg.
“The most important thing was that we got the victory which obviously gives us a little bit of an advantage going into the second leg.”
