Flanagan barge on Pienaar in the box infuriated the Reds manager, who couldn't work out why his side lost but admitted Spurs deserved to take home all three points
Steven Pienaar went down under a seemingly legitimate challenge from youngster John Flanagan early in the second half, but Webb awarded a spot kick and Luka Modric converted to wrap up a win for Spurs.
When asked on his thoughts regarding the penalty after the game, Dalglish told reporters: "I’m not here to sponsor the FA. It’s unhelpful to everybody that we can’t express our true thoughts and it’s even more disappointing that the officials get away scot-free without having the explain their decisions.”
However, the Scot admitted that the defeat, which saw Liverpool fail to find the net in the league for the first time this year, was deserved.
“I think they started better than we did; they kept the ball better in the first 35 minutes," he added. "We started to look a bit better but then early in the second half they got the second goal and it was difficult for us to break them down and from there it was difficult for us to penetrate their goal but having said that, I don’t think Pepe [Reina] was overly busy either.
“We never played as well as we can play and that’s the disappointing thing for the players because it would have been a fitting way for them to finish the last game at Anfield for the season for their efforts since January, but maybe it was too much for them.
“I don’t know why we lost. I’m sure there will be plenty of speculation but I can’t be specific about it. We don’t know why we didn’t start as well as we have done but I suppose like everything else that you get, these things happen."
The result means Spurs leapfrog Liverpool into fifth spot and a qualifying place for the Europa League, but Dalglish refused to be drawn on that.
"It’s not a race for fifth place, we’ve just got to look after ourselves," he added.
