Tottenham Hotspur are ready to step up their efforts to sign Dynamo Kiev attacking midfielder Andriy Yarmolenko, sources have told ESPN FC.

Yarmolenko, 25, has been a long-term target for Tottenham after catching the eye for club and country over the last few years.

The Ukraine international had the joint-most assists in the Europa League last season -- tied with Luciano Vietto with six -- as Dinamo reached the quarterfinals of the competition.
