Pepsi have been forced to issue an apology after an advertising campaign featuring a Cristiano Ronaldo voodoo doll attracted thousands of complaints.

The adverts, shown by Pepsi's sister company in Sweden ahead of Tuesday's 2014 World Cup play-off second leg against Portugal, showed a Ronaldo doll being tortured in different ways.

But Pepsi's attempt at humour backfired spectacularly when over 40,000 supporters joined a Facebook ground titled "Never drink Pepsi again".

Not only that, but the in-form Ronaldo went on to score a sensational hat-trick, to seal Portugal's place at next summer's tournament in Brazil at Sweden's expense.

Using their own Facebook page to apologise, Pepsi issued a statement which read: "We would never want to put the spirit of the competition in a negative light.

"We regret if people were offended by the posts; they were immediately taken down. We would like to extend our apologies to all concerned."

Portugal advanced to the 2014 World Cup finals thanks to a 4-2 aggregate victory.

Ronaldo and Zlatan Ibrahimovic scored every goal for their respective teams.
