5. Borussia Dortmund

This might be an odd affair. Barcelona and Dortmund might exchange managers at the end of the season. Robert is reportedly eyeing Thomas Tuchel to replace Luis Enrique. If he comes to the Camp Nou, Lucho might be destined for the Iduna Park.
Dortmund would be an interesting project for Luis Enrique. Thomas Tuchel has built a team capable of winning the Bundesliga. The additions of youngsters like Ousmane Dembele, Mikel Merino, Rapahel Guerreiro, Emre Mor and Alexander Isak have set the club up for a bright future.
While Dortmund have also invested in star names like Mario Gotze, Andre Schurrle and Marc Bartra, the club has also lost their icons, including Mats Hummels, Henrikh Mkhitaryan and Ilkay Gundogan. The club has still retained Pierre-Emerick Aubameyang, Marco Reus and Shinji Kagawa. Dortmund has also not let go of Christian Pulisic and Julian Weigl, despite interest from Premier League clubs.
The squad is a very good one and Luis Enrique will just elevate it to world-class status. He might also have an inclination towards Dortmund if he wants to move out of Spain. But it also might be the other way round.
