Luis Garcia's strike from close range in added time of the first half proved enough for the visitors as rain and wind swept across the arena in N17.
We struggled to get going in the first half but laid seige to the Liverpool goal as the second half progressed, although clear-cut chances remained at a premium.
Jermain Defoe forced a fine save from Pepe Reina, Dimitar Berbatov failed to get hold of the ball just six yards out and Steve Finnan hit his own crossbar as the Reds held on. We also had a goal rightly ruled out for offside.
Martin reflected: "If you look at the second half, the worse the weather was, the better we played.
"I thought we deserved a point out of it but we couldn't score. If we had kept a clean sheet in the first half people might have said we deserved to win, but two minutes before half-time we gave away a cheap goal and they punished us.
"That's always deadly, conceding a goal just before the break against a team like Liverpool, they know how to defend and hit you on the break.
"Having said that, I can only recall them having one chance in the second half and especially after the substitutions, we did better and better. We created enough to get something out of the game."
Martin Jol felt we deserved a point after our run of 12 straight home wins was ended by Liverpool in Saturday's 1-0 loss in the Premiership at the Lane.
