The flying winger hospitalised Crystal Palace left-back Jonathan Parr a year ago.
The 23-year-old, memorable for his FA Cup winning performance in the 2013 final against Manchester City, has joined on a three-and-a-half year deal and will add some much needed width to West Brom's style of play.
But his signing is interesting considering what Pulis was saying about the lad almost a year ago to the day.
Pulis was then Crystal Palace manager and he had just watched his side get dumped out of the FA Cup by the reigning champions Wigan, for whom McManaman played that day.
However one of the main talking points from the 2-1 result was an incident involving McManaman and Palace defender Jonathan Parr. The pair went up for a headed challenge on the brink of half-time and the Wigan winger led with his elbow. He made contact with the Norwegian left-back, sending him to hospital with concussion after being knocked out by the challenge.
After the game Pulis made these remarks on the matter, seeming to suggest the FA should step in on the matter. The Daily Mail reported:
"It looks as though the lad caught him. We’ll have to see it on TV but certain decisions went against it. Do the FA need to look at it? I don’t know but we’re very concerned."
Of course it was not the first time that McManaman found himself in hot water over a challenge. His sickening tackle on Massadio Haidara in March 2013 was roundly criticised at the time.
Of course Pulis knows a thing or two about tough football. His Stoke side stayed in the Premier League mainly because of their physical approach to the game. While he would have been annoyed to see his player injured in that game a year ago you can rest assured he never truly blamed McManaman.
He will want to see the exact same commitment from the winger, who has been unfortunate with his timing, rather than malicious in the mentioned incidents, that he saw at Wigan - regardless of what he said as an opposition manager a year ago.
