Harry Redknapp stressed the importance of staying in the tie after Saturday's FA Cup quarter-final finished goalless at Fulham.
It was a game high in intensity but with few clear-cut chances at Craven Cottage as both teams go into Sunday's semi-final draw.
We edged the first half as Mark Schwarzer kept out Niko Kranjcar's stinging shot and Peter Crouch's header but Fulham came closest after the break as Heurelho Gomes saved superbly from Zoltan Gera and Vedran Corluka sliced agonisingly just wide of his own goal in the final minute.
"You come here and you take a draw," stated Harry. "I'm not disappointed to come here and get a replay.
"You only have to look at their home record, they are solid at Craven Cottage and difficult to beat, so it was important for us not to lose.
"They've just knocked Shakhtar Donetsk, the holders, out of Europe and that says a lot about them.
"They are difficult to break down, well coached, well managed and not easy to play against, so to come away with a replay now gives us a good chance."
Harry described Wilson Palacios' display in central midfield as 'immense'. "He was outstanding for us, really strong," he added.
"I thought we kept possession well perhaps without creating as many chances as we would have liked, but both defences played well when they had to.
"We've got a big chance now playing at home but I'm sure Shakhtar felt the same when they went home for the second leg in the European game and it didn't work out that way. It will be another tough game but we're still right in there."
