SingTel and Samsung will be bringing in Manchester United's Rio Ferdinand and Manchester City's Sergio Aguero to Singapore for the SingTel Game On! Challenge on May 15 and 16. The two-day event is part of the lead-up to the Fifa World Cup Finals in June and July.

Four SingTel customers who purchase the Samsung Galaxy S5 LTE from April 11-May 8 can win a dinner for themselves and a friend with the two football stars. Other customers who purchased the handset can also get player autographs at a football carnival event on May 16, on a first-come-first-served basis.

Ferdinand and Aguero will be competing in an "Ultimate Selfie" challenge, taking photos of themselves while engaging in typical Singaporean activities as suggested by local fans via social media. They will then post their selfies on their own Twitter pages and encourage their fans to retweet them. The player with the most number of retweets will win the challenge.

Fan can participate by taking a creative selfie while enjoying a popular Singaporean activity and share it via Twitter using the #SGGameOn hashtag from April 23 to May 4. Ferdinand and Aguero will then choose their favourite selfie tweet and invite the lucky fan and a friend to join the other winners at the exclusive dinner.
