A 90th minute equaliser from Joao Palhinha earned the point for Spurs.
Frank said afterwards: "I think first half was good, I was happy with that in many ways. I felt we were on top, created two or three very good chances and got into a lot of dangerous situations where we didn’t create a chance where we should have created more.
"You know you are thinking, ‘yes this is very good, produce a lot of crosses and we are on track’. Football is not like Wolves please roll over. It is the Premier League and it is extremely competitive.
"So, you’re going into the second half and thinking I know it is not like you score, but I think OK, it could be good. I think the big change second half was probably their goal. It changed the momentum of the game and then at half-time they changed to a 5-3-2. I think that made it more difficult. Not that we didn’t know they could do it, but of course how do we get the message across to the players?
"Of course we got a little bit on about the pressure and getting it right, but the goal meant we probably lost a bit of structure and coolness. It took more passes to get up into the right positions, cross it from the right area or produce from the right area instead of a cross with your weaker foot or a difficult position and a shot from 30-yards even though they crowd scream shoot.
"I like the effort and mentality and I think it is huge actually and I meant that to get a point on a night where it is not perfect, especially not in the second half. Now that is two times in a row we come back. I think that tells a lot about the players. Yes, we want free-floating, yes we want more and we did not hit our highest performance level today, but when you are down at 90 plus and you get a point, I think that’s positive."
