Mauricio Pochettino has been a revelation since he joined Tottenham in 2014.
Prior to his arrival, Tottenham had appointed 10 managers in the previous 12 years and were consistently on the fringes of Champions League football.
However, the north London side has flourished under the Argentine's guidance, who has transformed his side into perennial title challengers.
He has also managed to achieve this with an impressive English core, with Danny Rose, Kieran Trippier, Eric Dier, Dele Alli and Harry Kane all playing pivotal roles for their side.
Despite their well documented struggles at Wembley, Tottenham are on course to challenge on multiple fronts again this season; having started impressively in the Champions League and having notched 17 points from their opening eight league games.
But things have not all been plain sailing at Tottenham.
Due to the club's wage structure, year after year Tottenham players are linked with big money moves away from the club, and at one stage last year Eric Dier was linked to Manchester United.
And after a 1-0 loss to Man United in 2016, Pochettino witnessed the former Sporting Lisbon man hugging United boss, Jose Mourinho.
In an exclusive interview with the Daily Mail, Pochettino has reflected on the incident and revealed how he reacted.
The Argentine said: "He (Mourinho) greeted Moussa Sissoko and hugged Dier. They passed by me en route to the dressing rooms, laughing, speaking in Portuguese. Maybe it is a common Mourinho tactic, but he put Eric in a compromising position. You cannot do that after a defeat.
"Are you friends with Mourinho?' I asked him. 'No, but I've known him a long time, from my time in Portugal... one of his godsons coached me. He always says hello.'
"I sat down with Eric after lunch on Monday and we chatted for four hours about the whole shebang: his agent, family, confusion.
"As for the Mourinho incident, 'What could I have done?' Eric asked me.
"He told me about United's interest since last summer  and I explained the situation to him clearly.
"Look, you aren't leaving because you signed a five-year deal with us in August. You're among the highest-paid players at Tottenham at the age of 22. You're important to us and you could become the best centre back in the Premier League.
"Ever since that conversation, Eric admits that he could have waited for Mourinho to be out of sight before heading to the dressing room."
Although this may have seemed like a minor incident, Pochettino's stance on the matter is justified considering they just suffered the disappointment of losing.
Despite United's interest, the Argentine's words must have convinced Dier to stay, and he has played an integral part in Tottenham's success in the past year.
Tottenham will be looking to enhance their title credentials when they host Liverpool at Wembley later today.
