Liverpool and Tottenham stars will face off for Croatia and England.
Tottenham Hotspur striker Harry Kane takes on a familiar opponent this week when England face Croatia in the World Cup semi-final.
He goes up against Liverpool's Dejan Lovren, who he embarrassed at Wembley earlier this season in a 4-1 club win.
Kane won't be short of motivation when England play Croatia, but Lovren's social media activity could have fuelled his fire.
The Croatia centre-back took a sly dig at Harry Kane, while the furore was escalating earlier this year as the Tottenham star claimed a dubious goal which took him closer to Liverpool star Mohamed Salah's tally in the Premier League golden boot race.
Kane is leading the World Cup top scorer charts with six goals so far, and he has a chance to extend his lead over four-goal Romelu Lukaku when he takes on Croatia.
Kane kept a dignified silence when Liverpool's players were having fun at his expense, and now is the time to make Lovren pay.
The Croatian is already up against it considering how he was taken apart by Kane at Wembley last year.
His Instagram dig won't have made his task any easier.
