England footballers Ashley Cole, Shaun Wright Phillips and Adam Johnson have all been promoting Samsung smartphones through Twitter, despite not directly revealing the promotional nature.
Cole has tweeted a picture of the three holding the new Samsung Galaxy S4, but failed to state whether it was a commercially motivated tweet.
In the tweet sent on Friday, Cole said: "Got hooked up with the new #GalaxyS4 @TMobile network is quick like me! #SimpleChoice pic.twitter.com/XOkzLjVW4l"
The tweet was then retweeted big Sumsung US alongside the message "@TheRealAC3 We're happy to have you in our league, Ashley. Welcome to the team."
Cole could be pressed to delete the tweet should it be referred to the Advertising Standard Authority which monitors promotional messages sent online, and demands that they are labelled as such.
