The interest in Barcelona defender Samuel Umtiti is expanding across the continent.

For many inside Spain, the France international is the best performing defender in the LaLiga this season.

Manchester United and Manchester City have expressed interest in Umtiti this month and Don Balon says they've been joined by two more European giants.

Bayern Munich and Juventus have also sought more information about Umtiti's situation.

Sparking the interest is not just Umtiti's form, but also his relatively affordable €60m buyout clause in his current deal.
