Jose Mourinho's first signing as Manchester United manager, Eric Bailly, has arguably been one of their best players of the season so far.
Not many Red Devils' supporters would have admitted to knowing much about the centre-back before the campaign started but few can complain about how quickly he has made the transition from La Liga to the Premier League.
The Ivorian's performances have been so good in his brief Man United career to date that he has already found himself being compared to another former Old Trafford legend.

Bailly's aggressive style and fearless approach has reminded many of Nemanja Vidic's spell as the rock in Sir Alex Ferguson's defence.
The Serb played a colossal role alongside Rio Ferdinand between 2006-14 and, until Bailly's summer arrival, the Red Devils had never really drafted in a like-for-like replacement.

In an interview published in Man United's matchday programme on Saturday, Vidic has been impressed with United's new No. 3.
"It's nice to hear [comparisons] and, from what I've seen, he is a very good player," he said.
"If he keeps going as he is, he will definitely have a great career at United. Of course, I'm glad that someone compares him to me and I hope he will be a player who does very well for us.
"He's strong and composed with the ball. He's a very confident player. He has a bit of everything. What I have seen in the first few matches is that we have a great player for the future and a player I would say we needed. He reads the game well. He already looks a big signing for us."
It was a busy summer of incomings at Old Trafford with the record-breaking return of Paul Pogba, Zlatan Ibrahimovic arriving on a free transfer and Borussia Dortmund's Henrikh Mkhitaryan all joining Bailly in Manchester.
But Vidic says it has been the defender who has made the best first impression.
He added: "I think he's already popular with the fans. Of the signings we've had this year, I think he's the one that has surprised everyone the most.
"He's 22 years old and he went into the club and looks at home straight away. That's outstanding for me. We know how many players come to England and need time to adapt and that, for me, is what is so impressive - he's 22 and he has adapted straight away and showed some confidence which is important."
However, having gone through the same experience Bailly is currently enjoying, the former United captain has stressed that the Ivory Coast international should not get too ahead of himself at this early stage of the season.
"The most important thing for a player of his age is to keep his feet on the ground," Vidic continued.
"The first few matches he really performed well and had so many compliments from everyone, but it's important to stay calm, keep doing what he was doing before and keep improving.
"If he continues to play like he does and stays focused, he can be here for many years and help the team be successful."
