Tunisia coach Roger Lemerre thought his side paid for being over-confident as they scrambled to a 2-2 draw against Saudi Arabia in their World Cup Group H opener on Wednesday.

Tunisia led at the break but only a Radhi Jaidi header rescued a point for Lemerre's side in stoppage time.

"I wanted three points and I got one," said the Frenchman after the game.

"We started well, but we did not start too confidently. Our mistake was to consider this game as something final - and the second half was not good for us."
