Liverpool are at Southampton on Friday, Spurs host Crystal Palace on Wednesday LIVERPOOL 2 TOTTENHAM HOTSPUR 1 March 31 (Reuters) - A 90th minute own goal from Tottenham defender Toby Alderweireld gave Liverpool a dramatic 2-1 win to maintain their lead at the top of the Premier League. Spurs keeper Hugo Lloris parried out a back post header from Mohamed Salah but the ball struck the Belgian central defender and rolled over the line. Liverpool are on 79 points with Manchester City, who won at Fulham on Saturday, on 77 points but with a game in hand. Roberto Firmino opened the scoring in the 16th minute getting between the Spurs central defenders to meet a perfectly shaped cross from left-back Andy Robertson with a firm header. Tottenham were well on top after the break however and it was no surprise when they drew level -- Harry Kane swinging a wonderful cross-field pass to Kieran Trippier whose low ball was flicked on by Christian Eriksen and Lucas Moura drove home the loose ball. Spurs could have made it even worse for Juergen Klopp's side five minutes from the end but Moussa Sissoko blasted over at the end of a dangerous counter-attack. Then came the late winner as Anfield erupted with relief and delight. (For more sports news and updates, follow Ahram Online Sports on Twitter at @AO_Sports and on Facebook at AhramOnlineSports.)
