Celtic manager Neil Lennon seeks Uefa clarification as to why Juventus players' 'cheating' went unpunished Lennon is aware of comments made by Mallenco prior to the 2010 World Cup finals in South Africa - where he was one of the referees - which were in striking contrast to his performance at Parkhead. It is most important for Fifa to make sure that all the referees whistle in the same way. This is the hope also of all the players, managers, fans and the media as well," said Mallenco. But really the key to the way a referee runs a game is not down to individual personality, it's down to the guidelines and the rules that are laid down by Fifa. The key is not the intensity of a match but the guidelines of the game. Lennon extended his complaint when he said: "Juventus are a brilliant team and they probably deserved to win the game but our players did everything right within the laws of the game. Juventus didn't. There are referee courses and one of the prime objectives is to stop the holding on set-pieces, particularly in the penalty area. The fact that there were additional officials behind each goal also perplexed Lennon. "If the referee goes up and says to them before the game 'don't overrule me" then they are basically redundant," he said. Again, we would like clarification. At the first corner my player has ended up thrown into the goal. That can't happen. Straight away the referee should have booked Lichtsteiner for that. There was a photo when Lichtsteiner was virtually pulling the shirt off his back and the ball was on the other side of the pitch. I was looking at it, everyone in the crowd was looking at it, the fourth official was looking at it and the referee was five, six yards away. Why does he not deal with it? There was a degree of consolation for Lennon in Celtic's performance against Dundee United, despite falling behind to a Stuart Armstrong goal after only nine minutes. Efe Armstrong, who missed Celtic's best opportunity and also gifted Juve two goals, made some amends with an unopposed header from a Kris Commons corner kick before Commons himself shot Celtic ahead midway through the first half. United were awarded a hotly disputed penalty when Adam Matthews was judged to have toppled Gary Mackay-Steven but Jon Daly's spot kick was saved by Fraser Forster and Celtic went further ahead with a Joe Ledley shot. After the break a Commons penalty and a Stokes double preceded a late Jonny Russell goal as Celtic romped home 6-2. Elsewhere, Motherwell beat Caley Thistle to leapfrog the Highlanders into second place with a 3-0 win at Fir Park where Michael Higdon's double was supplemented by a Nicky Law strike. Kilmarnock also won 3-0, against Hearts at Tynecastle, with a Paul Heffernan hat trick. A Leigh Griffiths penalty saw Hibernian past St Mirren in Paisley, while at Broadwood Rangers romped past Clyde with a 4-1 win.
