( CNN ) -- Arsene Wenger and Jose Mourinho 's uneasy relationship hit a new low as their ugly managerial spat overshadowed Chelsea 's 2-0 win over Arsenal Sunday to extend its lead at the top of the English Premier League . The pair squared up to each other and had to be separated by the fourth official after Wenger shoved Mourinho in the Chelsea technical area . The Arsenal boss was angered by Gary Cahill 's challenge on Alexis Sanchez but the pair 's seething rivalry has been a constant theme in the English football soap opera . Back in March , Mourinho labeled Wenger a `` specialist in failure '' and then his side rubbed salt into the open wound by thrashing Arsenal 6-0 . It was also Wenger 's 1,000th game in charge of the Gunners and he has now failed to beat his Portuguese nemesis in 12 tries . After the touchline incident , Chelsea proceeded to take the lead through Eden Hazard 's first-half penalty after he was fouled by Laurent Koscielny . Arsenal was always a factor in a closely-fought match at Stamford Bridge and might have had a penalty when former player Cesc Fabregas appeared to block Jack Wilshere 's shot in the area in the second half . Fabregas , whose signing by Chelsea from Barcelona dismayed Arsenal fans who hoped he might return to the Emirates , then set up Diego Costa for the clinching goal . His pinpoint pass , his seventh assist in the EPL this season , left Costa to score his ninth in seven games since moving from Atletico Madrid , another key Mourinho signing . The win left Chelsea five points clear of Manchester City at the top , with Arsenal in eighth , already nine points adrift . Both manager tried to play down the incident in post-match press conferences . `` Forget that ( the push ) . A football pitch is a football pitch , so no problem , '' said Mourinho . `` It becomes heated because this is a big game , big clubs , big rivals , an iportant match for both teams . These conditions make a game of emotions . Wenger was asked if he regretted the incident . `` What is to regret after that ? I wanted to go from A to B and somebody confronted me in between without any sign of welcome , '' said the Frenchman . `` B was Sanchez , to see how badly he was injured , '' he claimed . Earlier , Manchester United moved up to fourth with a 2-1 win over Everton at Old Trafford , but owed a lot to the goalkeeping heroics of David De Gea , who saved a first half penalty from Leighton Baines . United were already ahead through Angel Di Maria , but the visitors pulled level when Steven Naismith scored in the 55th minute . Colombian star Radamel Falcao put Louis Van Gaal 's men ahead just after the hour with his first goal in English football before De Gea denied Leon Osman with a stunning save to preserve three points for his side . Tottenham Hotspur is up to sixth , level on points with United and Swansea , after a 1-0 win over their manager Mauricio Pochettino 's former side Southampton . Christian Eriksen scored the only goal of the match at White Hart Lane in the first half . Ahead of the international break , Italian heavyweights Juventus and Roma played out a pulsating five-goal thriller in Turin . Both sides had won its opening five games in Serie A , but champion Juventus came out on top 3-2 thanks to a volleyed late winner from Leonardo Bonucci in the 86th minute . The first half saw a series questionable penalties for either side , the first two converted by Carlos Tevez for Juve and Francesco Totti for the visitors . Roma coach Rudi Garcia was sent to the stands for arguing the first penalty , but he would have been pleased to see Juan Iturbe put his side ahead on a breakaway in the 43rd minute . Juventus almost immediately drew level in first half injury time with another disputed penalty , put away by Tevez . The match looked headed for a draw until defender Bonucci proved an unlikely match winner , but there was still time for Alvaro Morata to clash with Roma defender Kostas Manolas and both were red-carded . European champions Real Madrid also scored a key victory Sunday , thumping Athletic Bilbao 5-0 in the Bernabeu , with Cristiano Ronaldo scoring a hat-trick and Karim Benzema adding a double . The win takes Real to within four points of leaders Barcelona after seven rounds of La Liga .
