Borussia Dortmund chief executive Hans-Joachim Watzke is no fan of Champions League group opponents Manchester City.

Indeed, Watzke wants them kicked out of the competition for their mega spending.

In a swipe at City, whose £350m deal with Etihad airlines (owned by the United Arab Emirates government who have close links with Sheikh Al Mansour) has come under UEFA scrutiny, Watzke insists: "UEFA must find the thin line between sponsorship and excessive back-door funding. They must show strength to expel big clubs.

"No tycoon should be allowed to pump crazy money into a club with sponsorship from five companies he controls. If that happens FFP will fail."
