Brazil legend Zico has given his picks for his favourite managers in today's game.
And the 67-year-old has revealed he still keeps an eye on football's top coaching talent.
"Guardiola and Klopp, but also Mourinho, Sarri, Simeone," Zico told Gazzetta dello Sport.
"There are many strong ones in Europe. Then you have to see what kind of players they have, what quality they have."
Brazil legend Zico says Manchester City are favourites to win the Champions League.
The Citizens hold a 2-1 lead over Real Madrid from the first-leg, with the second leg suspended due to the coronavirus outbreak.
But should the tournament resume, Zico thinks Pep Guardiola's men can go all the way.
He told Gazzetta dello Sport: "A month ago, I would have said Liverpool. But they dropped out suddenly and were eliminated.
"And now Atletico is a candidate, when you beat the favourites, and reigning champions, you can go all the way, you gain strength and awareness. Then I think the City and Guardiola are number one."
