"Elbowed him good", said Lovren, seemingly citing a challenge on Ramos during the game, while making a gesture with his elbow.
Lovren and Ramos have been in a war of words for some time, and just last week the Liverpool centre-half claimed that Ramos was made to look better by his teammates.More news: Ricardel reassigned from deputy national security post
In an Instagram Live rant after the match, Lovren also mocked Spain by laughing at the 3-2 scoreline before reportedly saying: "Go ahead and talk now buddy". Buddy! They are a bunch of p******'.
The Croatia worldwide then proceeded to cover the Spain flag on his match jersey, while pointing at the Croatia flag, and continued: "Only this side [Croatia] is worthy".

'He has many more mistakes than me but he's at Real Madrid, ' said Lovren earlier this month.
The 29-year-old Liverpool player took a further dig at Ramos on Friday morning, posting an image on Instagram of him towering over the Spaniard in an aerial battle along with the message "good morning Croatia!". I don't know if these things are said out of frustration or for other reasons. "But he plays for Real Madrid, when you do a mistake you win 5-1 or 5-2, nobody cares".
But Ramos had refused to be drawn into an argument. I'm not going to answer Lovren or those who want to win a front-page headline or news bulletin.More news: Withings reveals new Pulse HR fitness tracker
The win makes Croatia's upcoming meeting with England all the more crucial as a win at Wembley could see Lovren's team finish top of Group 4 and could also relegate England.
