Liverpool centre-back Kolo Toure has told the Liverpool Echo that he will not even speak to his brother and Manchester City star Yaya on Sunday before the two clubs meet each other in the Capital One Cup final at Wembley.
With the Reds defender's younger brother set to start in midfield for City, if the elder of two siblings is selected in defence by Jurgen Klopp it will be the first time that the two players have met in a major final during their careers.
The former Arsenal man admitted that there is no guarantee that he will be given the nod in the showpiece match after midfielder Lucas was selected ahead of him at centre-back in the Merseyside club's win over Augsburg on Thursday.
However, he revealed that whether or not he starts in the final, there will be no contact between himself and his brother before the match.
The 34-year-old told the Echo: "If we’re both out on that pitch then it’s going to be amazing to play against him in a final. I hope to face him. If not, the most important thing is that my team win.
"There will be no fraternising with Yaya before Sunday - no phone calls, no messages, no feeling. We are both going to war. We will both want to win and then we will talk after.
"Yaya is closer to some [in my family], I am closer to others. At the end one of us will come out on top."
Whichever team emerges victorious from the Wembley meeting, the Toure brothers will be adding another trophy to their already impressive collection in English football, having won the Premier League and FA Cup in their time together at the Etihad Stadium.
Kolo has also won a Premier League title with Arsenal, being a key figure in the Gunners' 'Invincibles' side which went the entire 2003-04 league season unbeaten, as well as winning two FA Cups with Arsene Wenger's team.
Meanwhile, Yaya has won another league titled and a League Cup at City since his brother left for Liverpool, and he also has a total of six trophies from his three years at Barcelona.
