Argentina were too strong for Poland on Wednesday night, with goals from Alexis Mac Allister and Julian Alvarez giving them all three points at Stadium 974.
Yet, in the closing stages of the match, Messi seemed aggrieved.
Lewandowski tried to tackle the PSG star, who he actually replaced at Barcelona back in the summer transfer window when he joined from Bayern Munich.
This resulted in play being stopped and, though the Pole appeared to reach out to Messi in order to apologise, the Argentina star was having none of it.
It speaks volumes about the 35-year-old's character that, even as his side battled their way into the round of 16, he wasn't happy. And it could, potentially, have stemmed from his missed penalty earlier in the contest.
