Saido Berahino vowed he will ignore any transfer speculation – and insisted he was acting "professionally" by not celebrating his FA Cup goal rush.

The West Brom striker hit four in Albion's 7-0 third round thrashing of Gateshead on Saturday but refused to crack a smile.

He scored an 11 minute hat-trick before grabbing his fourth at the death in Tony Pulis' first game as the Baggies' head coach.

Berahino has been linked with Liverpool and Tottenham but the Baggies have not had a bid from any club and the England Under-21 international insisted he will remain focused.

"I just have to do what I do on the pitch," said the 13-goal striker.

"I'm a West Bromwich Albion player and I've just got to perform for them and try to get as many goals as I can and contribute to wins.

"It's not really difficult because I just ignore the stories and I don't really read anything into it.

"Newspapers have said bad things about me so I'm not really fussed what they have to say about where I'm going or what will happen.

"I just ignore it all."

Berahino has five goals in two games after not scoring in his previous 11 outings and his lack of celebration against Gateshead raised questions over his happiness at The Hawthorns, but he dismissed any issues.

"I was just handling business and acting professionally and that's it," he said.

"There's no need for me to explain myself on not celebrating goals.

"It is what it is. I was just acting professionally and I didn't celebrate and that was it."

Berahino is waiting to discover whether he will be charged after being arrested on suspicion of drink driving in October.

New boss Pulis insisted he has handled players with problems before and said he can deal with Berahino.

"I have dealt with a lot of players who were different in lots of respects," said Pulis. "I have had players turn up late and had players not turn up at times. I have had players do things that would make your hair curl. But I have dealt with it and that is what management is about.

"If he has, he won't be the first boy to have problems off the pitch.

"I have signed players who have had massive problems off the pitch and worked with them and got the best out of them.

"We are all different."
