Tottenham are ready to make a first offer for Eintracht Frankfurt left-back Filip Kostic.

The Daily Express says Spurs had scouts watching powerful Kostic in the German club's Europa League final triumph over Rangers in midweek and they are now readying a summer bid for the player.

Serbia international Kostic, who can play as both a wing-back and as a winger, played a key role in Frankfurt's successful European campaign this season, and is rated at around £25million.

The former Stuttgart and Hamburg attacker has scored seven goals and provided 15 assists in all competitions this season for Eintracht - and in the Europa League alone has netted three times and managed six assists.

Tottenham were interested in Kostic in January but no bid was forthcoming then. Now though, manager Antonio Conte is intent on moving for a player he has admired for some time. Kostic still has one year left on his Eintracht contract, but a big-money move to the Premier League at his age would prove hard to resist.
