Mauricio Pochettino has had six games to acclimatise to Premier League football with his new club Southampton. Whilst his first few games in charge demonstrated little deviation from the ideologies and playing style of his predecessor Nigel Adkins, we are starting to see the Argentinian chief (or "Sheriff", if we are to use the nickname given to Pochettino at Espanyol) beginning to stamp his own mark on Saints.
Under Pochettino, the early signs showed optimism and promise. A draw against Everton and an excellent showing at Manchester United (despite losing narrowly) laid the foundations for a 3-1 win over champions Manchester United. Following the game Sir Alex Ferguson actually said that Southampton were the best team to have played at Old Trafford this season.
A draw away at Wigan followed, but two straight defeats have seen them dragged back into a relegation fight that Saints looked to be ascending away from.
So what influence has Pochettino had so far?
"I don't know if he's a crazy football coach, but he's very methodical, and always faithful to his ideas."
Biesla's sides play a very high octane and dynamic brand of football. Most recently, his Athletic Bilbao side drew heaps of praise for their vibrant, eye-catching style in the 2011-2012 season. Reaching the finals of both the Europa League and Copa Del Rey in the process. Espanyol under Pochettino were not far removed from trying to replicate this style.
You can bet that Pochettino will be out to replicate the ideologies of his mentor yet again in his new role. Like Bielsa, he is a stubborn tactician who has great belief that the way he is doing things is the right way. So for Saints fans, such significant changes early on could result in a case of things getting worse before they get better. With a relegation battle ahead, this could present a worrying run-in.
Here are some traits that Pochettino has looked to implement in his short time at Southampton and some thoughts on the implications they may have going forward:
