Salvation a warning for Real-Ronaldo

Cristiano Ronaldo warned Real Madrid will be punished if it doesn't improve on its performance in an edgy 2-1 win over Sporting Lisbon to start its Champions League defence.

Alvaro Morata headed home the winner four minutes into stoppage time at the Santiago Bernabeu on Wednesday after an 89th minute Ronaldo free kick had canceled out Bruno Cesar's opener for Sporting.

"It is a warning that in the coming games we can't start so softly because if we do they can make a fool of us," Ronaldo told BeIN Sports.
