Andre Villas-Boas cut a furious figure in the Tottenham dugout as his team had three goals ruled out in their 0-0 draw with Lazio in the Europa League.
The Italian giants came to White Hart Lane on the back of a five-match winning streak, but they were outplayed for large parts of the Group J clash, which Villas-Boas clearly feels his side should have won.
The Portuguese manager, who earned his first win as Spurs boss on Sunday, was livid at referee Ovidiu Alin Hategan for disallowing Steven Caulker's goal deep into the second half.
The centre-back leapt high to head home Gareth Bale's corner but the Romanian official ruled he had pushed his marker in the lead-up to the goal, a ruling which caused Villas-Boas to fling his arms up in the air in an angry manner.
He had already seen Clint Dempsey's header ruled out for a marginal offside and Bale also had a strike chalked off after latching on to the impressive American's through-ball.
Sandro and Bale both missed close-range headers and Villas-Boas will probably look back at this as a missed opportunity ahead of what is expected to be a tough trip to Panathinaikos next month.
Lazio could have stolen the game at the end through Stefano Mauri and came within a whisker of going ahead in the first half when Alvaro Gonzalez beat Hugo Lloris but saw his shot rattle the woodwork.
Aaron Lennon, captain for the night, Gareth Bale and Caulker all impressed while a clean sheet for debutant Lloris is another plus point.
Lazio had no answer to the pace of Bale and Lennon, who were dominating the flanks.
Andre Dias was booked for hacking down Bale after 61 minutes and Gonzalez saw yellow a few minutes later when he took Lennon out after the winger had given him the slip.
