Swansea City boss Carlos Carvalhal has launched a furious attack on Renato Sanches.

Sanches, on-loan from Bayern Munich, caused fury among Swans fans when a picture of him launching his own emoji appeared on his social media channels the day after Swansea's defeat to Southampton had put them on the brink of relegation.

“I heard about it, I have not seen it," said Carvalhal when asked about the emoji storm.

“But I say to the players about social media all the time.

“The majority of them are not dealing with their social media, they are dealing with people who support them, and I say not to do it because you are football players and sensitive about the fans and so on.

“When we put things not about football in someone else's hands they think they are doing a good thing.

“But they are doing one of the most stupid things in the world.

“So I have not spoken to Renato, but I believe this is what has happened. I have seen it happen before in my career and it has happened again.

“I always tell players not to put social media in the hands of other people. You can give it to someone with experience who will know what to do, but many give it to their friends who can be stupid and create these situations.

“I have seen it happen often, trouble with social media, even though you tell players to be careful because it is their face on it."
