London - Leeds United climbed back to the top of the Championship in dramatic fashion on Tuesday after Jack Harrison's late goal snatched a 1-0 win at Reading.
Leeds' second late winner in four days earned them a fourth successive win as they moved one point above second-placed West Bromwich Albion, who host Bristol City on Wednesday.
Marcelo Bielsa's side recovered from a slow start to push Reading onto the back foot and Stuart Dallas hit the crossbar after the interval.
They snatched the winner three minutes from time when Harrison headed home Helder Costa's deflected cross.
"Of course when you are top it's better than another position in the table, but also it's true today it doesn't mean a lot," Bielsa said.
"The players made a big effort to keep the intensity in the match. The physical performance and skill of the players is something we have to congratulate them on.
"It was a tight match. It was difficult for us to create danger in the first half. In the second half we were better. We did enough to deserve the win."
Fulham crushed Derby 3-0 at Craven Cottage to move into third place.
Goals by Bobby Decordova-Reid and Aleksandar Mitrovic in the first half and a late third by captain Tom Cairney gave Scott Parker's side a third consecutive victory.
Although they have won their past five home games, Derby are without a league victory on the road since the opening match of the season.
