The in-form England U-21 star has already notched five Premier League goals this term, leading to talk that Spurs are ready to launch a January raid for his signature.
With his fine tally and his future potential, the Lilywhites are ready to pay around £15m for the 21-year-old, but Irvine believes that in the current market his Baggies star is worth much, much more than the Londoners are reportedly willing to pay:
“It doesn’t sound a lot. I would be absolutely astonished if anyone could sign Saido from us for £15m,” he is quoted by the Daily Mail.
“You look at some of the fees going around in the transfer market that’s just been, everybody seems to start at £7m.
“Ross McCormack went for £11m Championship to Championship. What the right figure is I have absolutely no idea and I wouldn’t make the decision as far as that was concerned.
“But £15m doesn’t sound like a lot of money for a talented, young, English player with great potential who is playing really, really well in the Premier League at the moment and who is scoring goals. It would have to be higher than that.”
But Irvine went on to say that if Berahino goes continues to perform at his current level West Brom may be unable to keep him at The Hawthorns:
“That’s something which could happen, there’s no question about that but I don’t want him to play poorly so that they don’t come,
“I am desperate for him to play really well and if that means other clubs come and start knocking on the door then the club will make a decision on whether these clubs are making the right kind of offers or not.
“If Gareth Bale can be prised away from Tottenham I think it means every player has got his price.”
