Chelsea boss Jose Mourinho reportedly travelled to Ukraine on Monday to watch Dynamo Kiev forward Andriy Yarmolenko in action against Spain.
The Portuguese was spotted in the stands during last night's Euro 2016 qualifier, a game that Spain won 1-0 courtesy of a first-half header from Mario Gaspar.
It was immediately speculated that Mourinho was there on a scouting mission and according to Sport, it was Yarmolenko that the experienced boss went to see.
The 25-year-old, who has also been linked with Barcelona, is said to be valued in the region of £18m by his current club.
Since breaking into the Dynamo Kiev first team in 2007, Yarmolenko has scored more than 100 goals for the Ukrainian outfit.
