Andre Villas-Boas feels the referee got it right in two decisions that went the way of Tottenham on Sunday.
Cardiff City were adamant Spurs keeper Hugo Lloris handled the ball outside the area as Fraizer Campbell looked to round him in the north London clubs eventual 1-0 at the Cardiff City Stadium.
A second decision disallowed Ben Turner's headed goal as Aron Gunnarsson appeared to impede Lloris and even though Cardiff cried foul, Villas-Boas was happy with the calls from Mark Clattenburg.
"I haven't seen it (the first incident), but I understand he was right on the limit. I'm not sure if there is some controversy there," he said.
"Most people I have spoken to told me his hand is right on the line. I think if that is the case the referee made the right decision."
Of the disallowed goal, he added: "I think it was a foul for holding Hugo's arm. We spoke about it between us at half-time and he said he would have been fine if he had not been fouled."
