#4 Thomas Tuchel
Thomas Tuchel is the current manager of PSG and he has previously managed Bundesliga giants Borrusia Dortmund, guiding them to DFB Pokal Cup triumph in his final season. Tuchel's style of play is based on possession-based football but he can switch to counter attacking football as well, as shown by his time at Dortmund
His record in Ligue 1 is fantastic, to say the least. With zero defeats and 18 wins, PSG are at the top of the table, scoring 66 goals in the process. He also managed to top his Champions League group were he faced the likes of Liverpool and Napoli. If Roman Abramovich wants Chelsea to play an attacking style of football, Tuchel should be a good option as he has experience at the top level and he has proved that he can deliver trophies as well.
For Tuchel, it would be a tempting offer to manage a Premier League club. His work at Dortmund is admirable but at PSG he has next to no domestic title challengers to worry about. The Premier League would indeed prove to be a good testing ground for a manager of his calibre and he would relish the challenge.
