It was a quite frantic few days at Tottenham Hotspur last week as Mauricio Pochettino was given the sack before being replaced by Jose Mourinho just hours later.
So far, the move seems to have worked a treat with Spurs ending a ten-month winless streak on the road before coming from two goals down to thump Olympiacos.
There seems to be a refreshed vim and vigour about the whole club, and, while it is still very early in his tenure, Mourinho seems to be making all the right moves.

Changes to the training regime
In the gloomy final days of the Pochettino era, training had reportedly become stale and tedious and their poor results were considered a consequence of the training squalor.
The moment Mourinho arrived though, that all changed. The Portuguese injected new life into training sessions focusing on how the team can tighten up in defence and defend the entire field as a unit.
'There's more of an edge to training,' a source stated.
There has also been greater emphasis placed on recovery, which the playing staff are said to be heavily in favour of.
Be more streetwise
This was reported to be one of Mourinho's first instructions to his new squad.
The Special One believes a small shift in attitude in terms of the way Spurs approach games can turn them into winners.
Mourinho has always been one for the calculated approach but loves to instil a sense of cunning amongst his teams.
When a ball-boy rushed to deliver a ball that would ultimately result in Harry Kane smacking home on Tuesday night, it became clear that the message was already getting through.
Cheerful and involved
Pochettino had begun to employ a bizarre approach to training towards the end of his tenure.
The Argentine very rarely attended sessions, choosing instead to watch from the clubs canteen at the training complex.
He was said to be cranky and disengaged and the whole mood around the club had become rather sombre as a result.
Mourinho, on the other hand, dived straight in - getting down and dirty at training while sharing jokes with his players and staff.
The new sessions are said to be lively and engaging and Mourinho's insistence on personal chats with his players has reinvigorated the whole place.
A winning mentality
"Believe in me, and we'll become winners."
That was the gist of Mourinho's opening address to his new squad as he seeks to end a 12-year long trophy drought.
Mourinho was careful not to disrespect what had been achieved under his predecessor but pulled no punches when telling his players that he could turn them into a group of winners.
Players such as Harry Kane were are said to be happy with the appointment of a proven winner and, while their main task will be to get their top-four charge back on track, they will be hoping Mourinho can finally deliver some silverware.
Leaning on Kane
Mourinho quickly identified the importance of Tottenham's talismanic forward, having several one-on-one talks with the England skipper.
Tapping into Kane's knowledge could be incredibly important as Mourinho knows just how vital it is that Kane remains happy at the club.
Speaking after their come-from-behind win over Olympiacos, Kane said:
"Obviously, me being one of the leaders in the team, he looks to me for feelings and advice on the
"When you are winning games, it definitely helps your relationship. Hopefully, we can build a strong relationship."
It is still far too early to truly judge Mourinho at Spurs, but, if the first eight days are anything to go by, there are going to be a lot of smiling Tottenham fans over the coming months and years.
The Special One is back folks, and he means business.
