If you look at Stoke and Crystal Palace during his time at the club, there were similarities, will it be the same at The Hawthorns?
Tony Pulis wasted no time in making some changes when he became the head coach of West Bromwich Albion - he went straight into the transfer market and brought in the likes of Callum McManaman and Darren Fletcher.
It sort of gave you a flavour of what Pulis thought the Baggies needed. A bit of width, more experience in the middle of the park as he tried to add to the attacking options of his side as well as bringing in someone who can exert some control over the midfield's performance.
The question is whether he feels further need for strengthening in those areas in the future, or maybe he will look elsewhere.
If you thought they needed a striker, the upturn in form from Brown Ideye could make you think otherwise as he seems to have found his scoring touch under the former Stoke City and Crystal Palace boss - as Ideye and Berahino are forming a very effective partnership up front.
There could be concern over the future of Berahino as the 21-year-old forward had been linked with a move away from the club earlier on in the season, while Victor Anichebe has barely had a look in since the arrival of Pulis - another striker could be on the cards.
A signature element of a Pulis side at both Crystal Palace and Stoke City was a steely central player, where that was at centre-back or in a holding midfield role. Two big, powerful presences that come to mind at both of his previous clubs are Mile Jedinak and Ryan Shawcross respectively.
The Baggies have good players available in those positions but do they really have someone of that ilk? Jonas Olsson looks the type of player that Pulis likes, and while Claudio Yacob has impressed, is he as much of a presence as Pulis would like? It would be interesting to see what he does in that area of the field.
Another aspect is pace. There seems to be a lot of it in the West Brom side, especially at the top end of the field - it will be interesting to see if Pulis takes West Brom in the same direction when it comes to style as he has done previously.
