The Three Lions’ dream of becoming European Champions ended on Sunday evening (11 July) in a nerve wracking penalty shootout after a 1-1 draw at Wembley.

In the video, posted on Monday (12 July), Grealish came up to him and presented Olly with his boots from the match.
Alongside the clip and a picture of them together, the caption read: "With all the negative, horrible stories going about let’s see if the media post about this amazing, beautiful moment that @jackgrealish did for my son Oliver.
"Super Jack is an absolute CLASS act on and off the field. Took time with photos with Oliver then asked if he wanted his boots.
"This is a moment I will cherish forever. Thank you Jack."

He said: "I said I wanted to take one!!!! The gaffer has made so many right decisions through this tournament and he did tonight!
