Maurizio Sarri may have only been at Chelsea for just six months, but he's already made quite an impression at Stamford Bridge.
Under the Italian, the Blues went unbeaten in their first 18 competitive matches and have arguably been exceeding first-season expectations.
Chelsea did go through a bit of a rough patch ahead of Christmas, but came out of the busy fixture list in good shape - and sit fourth in the Premier League.
That's not bad for a side that are still learning and adapting to Sarri's signature style of play.
Although things are going well on the pitch, the club are often still criticised for how they handle their business off it - particularly in terms of transfers.
In fact, a number of stories surrounding Chelsea are starting to dominate the January window - with the futures of Cesc Fabregas, Callum Hudson-Odoi and Alvaro Morata currently unclear.
There's genuine concern that all three of those players could be leaving the club in the next few weeks - and most of that concern is around young Hudson-Odoi.
The west London club have already rebuffed one serious bid from Bayern Munich, and Sarri is desperate to hold on to the 18-year-old, claiming this week that he's ready to make a league start.
However, it's unclear if the Blues will be able to hold on to their starlet, especially if reports of Bayern coming back with an improved bid are true.
If boss Sarri was given full control of Chelsea's transfer policy, he'd almost certainly make keeping Hudson-Odoi and the club's other young players a priority.
But interestingly, there's another area that he'd make a major change to as well - and it involves how Chelsea treat their older players.
WHAT THE BOSS WOULD CHANGE
Speaking on Monday, Sarri revealed that he would scrap Chelsea's policy of only offering one-year deals to players over the age of 30, saying that he would offer contracts on a player-by-player basis.
"I haven't a club so my opinion is not important," he said, per the Mirror.
"My opinion is it depends on the situation, I think. The situation is not the same for every player over 30 so it's my opinion. If you are able to buy Chelsea we can discuss [changing it]."
Although he's not directly saying anything regarding 31-year-old Fabregas, it seems that Sarri, if given the opportunity, would maybe have tried to tie the Spaniard down to a longer deal.
Of course, this hasn't been the case - and it looks almost certain that the midfielder will link up with Monaco later this month - regardless of whether Sarri wanted to keep him or not.
