Toby, who plays for semi-professional football team Hashtag United FC, was clearly delighted to encounter one of the Premier League's most legendary players.
And smartly-dressed Keano, looked equally chuffed to meet Toby who has strong Irish connections as his mum hails from Mayo.
Rumours that Roy would make his reality TV debut in recent months by joining I'm A Celebrity were sadly quashed as he is sticking to Sky Sports duties where he is now one of the most popular pundits on television.
Most recently the Irishman got into a heated debate with Jamie Carragher over Man United and Cristiano Ronaldo which proved box office for viewers.
But on his own Instagram page he has often shown a softer side to his gruff persona.
He recently posed with daughter Caragh in a lovely snap in which the former professional footballer wished her a happy birthday.
The soccer pundit also shared other pictures on his Instagram page showing her doing a jigsaw with her dad as a small baby, and posing in front of a car as an adult.
In one happy snap she has a pen stuck up her nose.
Keano posted the picture alongside the words: "Happy birthday no. 2."
Since joining the social media site in February this year, he has amassed a whopping 1.8m followers.
He also reveals a less serious side in some of the posts, with one showing him dressed up as Chase from Paw Patrol.
And appearing alongside some very young relatives, he said: "Available for party hire. I don’t like parties or kids but the pool needs heating."
He and Micah Richards have also become an unlikely double act on Sky Sports over the last couple of years and the duo recently served up another social media hit.
Former Manchester United captain Keane has formed a bond with ex-Manchester City defender Richards on screen and the pair filmed some popular YouTube videos last summer.
Now they have been taking advantage of relaxed Covid rules in the UK to enjoy a Christmas party, with Richards' trademark laugh booming through on the clip.
sundayworld.com spoke to Richards earlier this year about his friendship with Keane, as he suggested their bond has grown after a shaky start.
"I can't compete with Roy Keane in terms of medals, so I try and have a different approach when we are working together," Richards told us.
"There is this perception about him, but let me tell, you, he is a great laugh to be around.
"I've seen people go on there who have tried to fight fire with fire with him. You're not going to win that battle. So I try to soften him up around the edges and have a bit of fun with him off air so that when we go on air, it comes out on air as well.
"Honestly, I love working with him but it's hard for us now because every time you go on air people expect there to be fireworks. It's not going to be like that.
"He probably wants to be a manager again further down the line and I don't want to be the pundit that's always laughing and joking. We are just trying to get the balance right, but working with him is absolutely amazing.
"He is a hard man, but more importantly, he is an actual a genuine bloke and he has been a joy to work with on Sky."
