The 20-year-old has risen to prominence in recent weeks after the West Bromwich Albion forward scored the winner in a 2-1 victory over Manchester United in September.
Baggies boss Clarke handed Berahino, whose contract is set to expire at the end of the season, his full Premier League debut in Sunday’s 1-1 draw with Arsenal.
The former Liverpool assistant manager reckons the forward will have a big future in the game – but has warned Berahino not be distracted by speculation.
“It’s just speculation and the speculation is rubbish,” Clarke said at the Asian Football Awards.
“He’s under contract with West Brom until the end of next season, so we’ve got plenty of time to sort out Saido’s future.
“He’s a sensible boy. He understands that all the rewards and riches come with hard work and he has to just concentrate on his football and let other people worry about his contract situation and whatever.
“Saido has got a big future in the game and all he can do now is work hard and make sure he is still a top player in 10 years’ time.”
