Paul Pogba has leapt to the defence of Zlatan Ibrahimovic, saying his former team-mate is "the last person I'd think of as racist" after his clash with Romelu Lukaku.

Ibrahimovic and Lukaku traded insults in heated exchanges during Inter's 2-1 Coppa Italia quarter-final derby win over Milan on Tuesday.

Both players were booked following a confrontation late in the first half and they had to be separated as the furious row continued after the whistle for half-time was blown.

Ibrahimovic, who was sent off in the second half for a second bookable offence, appeared to tell Lukaku to "Go do your voodoo s***, you little donkey."

The Milan striker on Wednesday denied he was guilty of racially abusing Inter's leading scorer Lukaku, who equalised in the second half before Christian Eriksen scored a late winner.

He tweeted: "In ZLATAN's world there is no place for RACISM. We are all the same race – we are all equal!! We are all PLAYERS some better then [sic] others."

Pogba, who played alongside the prolific Swede and Lukaku at Manchester United, later stated there is no way Ibrahimovic would subject anybody to racial abuse.

"Zlatan... racist? He loves me too much so he's the last person I'd think of as racist! Come on, don't joke with that one!" the United and France midfielder posted on Twitter.
