The pair were seen to be exchanging words during the friendly after Pogba lost possession, but the Juventus midfielder has denied talk of a rift with his club and international teammate.
"I wanted to change the play but I did not see the pass, so I kept the ball. I slipped and lost the ball," he told RMC.
"Pat did not come over to scold me; he came to encourage me. There was no argument.
"As I often say, this is my 'Uncle Pat' and he came to tell me it was not serious and that I should continue as I was doing, as he always done in the past. I was a little bummed about losing the ball, but football is like that."
Pogba scored France's second against Portugal after Real Madrid striker Karim Benzema had opened the scoring.
