There's one thing you don't do if you're Cristiano Ronaldo's teammate and that is steal his goals.
The Portuguese is obsessed with scoring and anyone attempting to nick one off of him is usually met with a cold, icy stare from the Juventus man.
And former Arsenal midfielder Aaron Ramsey will certainly not be in Ronaldo's good books this evening.
The Welshman was on hand to score his first Champions League goal for Juve, prodding the ball over the line after Lokomotiv Moscow's 'keeper spilled a Ronaldo free-kick.
However, the ball was going to cross the line, which would have been Ronaldo's first goal from a free-kick for Juve.

But Ramsey was having none of it and even though the Welshman pointed in Ronaldo's direction after scoring, he was awarded the goal.
Oh dear, Aaron. But if you're a midfielder with an eye for goal - like Ramsey is - surely you have to go for the ball, even if Ronaldo will blank you for a couple of weeks?
Juve went on to win the game thanks to a wonderful solo effort from Douglas Costa in stoppage-time to seal a 2-1 victory in Moscow.
Ronaldo himself was substituted in the second half by Maurizio Sarri and with Ramsey stealing his goal, it was far from a great night for the legendary Portuguese forward.
One other famous example of a player trying to steal a goal off Ronaldo came courtesy of former Manchester United winger, Nani.
While playing for Portugal back in 2010, Ronaldo slalomed his way through Spain's defence, dinking the ball over the 'keeper and sending it goal bound.
So what did Nani do, he headed home from an offside decision and the goal was disallowed, much to the despair of Ronaldo.
