Here is my take on the possible next Man Utd manager.
Mauricio Pochettino:
Not impressed with Pochettino’s stint at PSG despite having the best of the world players- Messi, Mbappe, Neymar, Ramos, Di Maria, Donnarumma, Navas. What more do you want to be the invincible team in Europe? 
Pochettino has two Ligue 1 trophies so far (last season lost the Ligue 1 title to Lille) but has the lowest win rate among his peers contesting for the Man Utd position.
Pochettino’s Overall Record:
Clubs: Espanyol, Southampton, Tottenham, PSG
Points per game: 1.67
Win rate: 48.6%
Loss rate: 29.9%
Goals per game: 1.69
Goals against per game: 1.17
Trophies: 2 (Coupe de France, Trophee des Champions)
Following yet another Champions League collapse this season at the hands of Real Madrid, the Ligue 1 title is the only saving grace for Mauricio Pochettino now.
Ajax boss Erik ten Hag:
Ten Hag, who joined Ajax in 2017, has enjoyed a successful stint at the club, having won five trophies there including two league titles.
Ten Hag is known for his attack-minded style of football, leading Ajax on a dream run to the semi-finals of the Champions League in 2018-19, where they dramatically lost against Spurs.
The Dutch club had won all their group games this UCL season, however Benfica pulled off a surprise 1-0 win at the Johan Cruyff Arena to end Ajax’s impressive UEFA Champions League run.
This season, Ajax stand atop the Eredivisie table having won the title for the past 4 years.
Erik ten Hag Overall Record:
Clubs: Go Ahead Eagles, Bayern Munich’s reserve team between 2013 and 2015 while Pep Guardiola was manager of the first team, Utrecht, Ajax
Points per game: 2.08
Win rate: 64.04%
Loss rate: 19.1%
Goals per game: 2.41
Goals against per game: 1.08
Trophies: 5 (Eredivisie x2, KNVB Cup x2, Johan Cruyff Shield)
Playing style:
Underpinning Ten Hag’s philosophy is a desire to press aggressively and win the ball back quickly. The role of the defensive midfielder is key to his system in helping to shield the back four.
In his own words, Ten Hag says success is less to do with formation, and more to do with basic principles. He told DutchSoccerSite: “It’s not even about systems. It’s about what you do in possession, when you lose possession and in those turn around moments. And you need to be able to change that up.”
He added: “The players’ qualities determine how you play.”
He also has a relentless desire to win, again and again. Ten Hag explained: “Good ain’t good enough. We need to get better. Push boundaries.
Thomas Tuchel:
Tuchel departed PSG with a record of 95 wins, 13 draws, and 19 defeats in 127 games, with the best win percentage in Ligue 1 history (75.6%) and the highest average of points per game (2.37, tied with his predecessor Emery). I never understood his sacking at PSG, probably conflicts with management played a role.
Tuchel has had an incredible run since his appointment at Chelsea. Tuchel’s achievements in 13 months at Chelsea:
FIFA Best Men’s Coach
UEFA Mens’s Coach of the Year
German Manager of the Year
Champions League winner
Super Cup winner
FA Cup finalist
League Cup finalist
Tuchel’s Overall Record
Clubs: Mainz, Borussia Dortmund, PSG, Chelsea
Win rate: 58.5%
Loss rate: 23.07%
Goals per game: 2.05
Goals against per game: 1.11
Trophies: 10 (DFB-Pokal, Ligue 1 x2, Coupe de France, Coupe de la Ligue, Trophee des Champions x2, Champions League, UEFA Super Cup, FIFA Club World Cup)
There are few of them in world football who can compete with Jurgen Klopp and Pep Guardiola, whether it’s in this league or the Champions League and Thomas Tuchel is one of them.
With the current uncertain times at Chelsea there are speculations about the prospects of the current team. However, I think Tuchel’s story at Chelsea is still incomplete. He is the perfect fit for Chelsea in my opinion, can take the club to even greater heights and establish his legacy at Stamford Bridge.
My other pick would be Luis Enrique
Messi described Luis Enrique as one the two best managers he has played for, the other being Guardiola. While Guardiola maintains that though he has played against many great footballing sides as a manager, Luis Enrique’s Barcelona and Jürgen Klopp’s Liverpool were the best he has ever faced.
It is understood that United are a big admirer of Luis Enrique, but he might not be willing to leave the Spain job before the World Cup in November.
Enrique Overall Record:
Clubs: Roma, Celta Vigo, Barcelona, Spain
Points per game: 2.06
Win rate: 63.6%
Loss rate: 20.7%
Goals per game: 2.38
Goals against per game: 1.003
Trophies: 9 (La Liga x2, Copa del Rey x3, Champions League, UEFA Super Cup, FIFA Club World Cup, Supercopa de Espana)
