Without google, name a starting attacking player at Monaco this season. (if Falcao is not dead, probably him).
Jardim built a team with Fabinho, Mendy, Mbappe, Lemar, B.Silva. 5 massively rated and all at top club around Europe. Don't think any manager would cope well losing those players and having a budget to replace them with shite.
Jardim played enough beautiful football and winning league in 2016 to prove he has what it takes to be a top manager.
It it was up to me I'd give him the job tomorrow as caretaker with the option of a full time position should he turn things around at the club. By turn things around I wouldn't expect him to make top 4 (Jose's mathematically fecked that goal, along with a new manager, new squad, not his players etc.. all against him). But if there was visible signs of a happy more confidence squad, playing better football and entertaining the fans then I would give him a 3 year deal in the summer.
You could argue why on earth would he take a caretaker job. Well, we're not a small club, we're one of the biggest. Opportunities like these are golden to managers, it's the career goal.
