The West Brom forward handed in a transfer request with the north London side interested in him, as reported by the Guardian among many others, but it was rejected by the Midlands outfit.
Pulis, however, feels the young forward was simply showing ambition by wanting to join Spurs - even criticising the lack of quality and ambition shown by some of his other players. The Welshman's only bugbear was the 'immature' way in which Berahino handled the situation.
The West Brom boss is quoted as telling reporters: "My big issue with Saido is he is immature at times in the way he reacts. Something he has done in the two windows since I've been here, his reaction has not been sensible.
"For him to want to go to another club, to have the ambition to do that, I wish there were more players in my dressing room who had the ambition and quality to want to do that. But the problem with it is the way he has gone about it and the way it has been managed."
Should the West Brom forward feature against Southampton this weekend - which looks likely based on Pulis's tone and comments - it will be interesting to see how the Baggies faithful react but also how the 22-year-old himself responds.
When Berahino took to Twitter on Deadline Day, he appeared to state that he won't play for West Brom again. There was a key word missing, though, as Berahino's tweet was very poorly written grammatically.
Did he, in fact, simply mean he won't confront chairman Jeremy Peace, after all? How the former Tottenham target behaves against the Saints will give a keen insight into his current frame of mind.
