Rice recently made his competitive international debut in England colours, despite being capped by the Republic of Ireland in three friendly matches.
It prompted an angry response from McClean, who played alongside the West Ham utility player in each of those outings and told RTE: "He said he was a proud Irishman. Then he said he was a proud Englishman. If he's both... good luck to him but I don't buy it. I think you're either one or the other.
"It's not just Declan, it's anyone else. If you're not proud to be here and we're a stepping stone then sod off and play for someone else."
But the following West Ham supporters have taken issue with McClean's criticism - with some pointing out that the Stoke winger also changed his international allegiance from Northern Ireland to the Republic.

James McClean clearly is as stupid as he looks What a giant tosser!— Richard Faasen (@RichFaasen) 27 March 2019

Would love to see Declan Rice come out with a HARD tackle on McLean when they next meet this premier league season. Oh wait....— Marshall⚒ (@MrshllClrke) March 27, 2019
McLean is a hypocrite. Played for the North now professes to be Irish. He's at best an average championship player unfit to lace Declan Rice's boots and should concentrate on improving and keeping his mouth shut.— ⚒D-Hammer ⚒ (@lex_e_con) March 26, 2019
McClean later justified his Rice comments, explaining: "I was with Derry City when I got the call-up to play for the North and I turned it down because it's not my country, it's never been my country. I'm an Irishman."
The 29-year-old, for whom Stoke are said to have paid £5 million to sign from West Brom last summer (Transfermarkt), has won 60 caps for the Boys in Green.
Rice was born and raised in London, spending the bulk of his youth career on the books of West Ham's London rivals, Chelsea, before joining the Hammers after his release by the Blues.
The 20-year-old has since become a regular in West Ham colours, playing 64 times since 2017.
