England reported the incident which took place shortly after the half-time whistle, when Poland defender Kamil Glik appeared to pinch the neck of Kyle Walker

FIFA have launched a full scale investigation after FA chiefs claimed Kyle Walker was racially abused during England’s World Cup qualifier with Poland.

Poland defender Kamil Glik is alleged to have made a remark or gesture in a bust-up with Walker which left England defender Harry Maguire incensed.

Poland players have strenuously denied any wrongdoing; Glik was alleged to have pushed Walker several times before the flare-up.

Football Association officials Emily Webb and security officer Tony Conniford made accusations to fourth official Daniel Schlager at half time during the game in Warsaw.

The English FA have yet to go public as they try to ascertain exactly what was said or done and whether it was an allegation of racism.

Poland team manager Jakub Kwiatkowski was called from the home team’s dressing room as the FA made the allegation, UEFA delegate Joao Morals took statements and gave the go-ahead for the game to continue.

Glik, who was also booked, said: “There was some scuffle, later I wanted to shake Walker’s hand but he didn’t accept it. There was some verbal scuffle but nothing more happened there.”
