A veteran of 963 United games and the current assistant manager to Louis van Gaal, Giggs was talking to the Telegraph's Sam Wallace following the 25th anniversary of his debut against Everton as a 17-year-old.
Giggs won 34 trophies in his time as a player, but apparently that's not enough to convince Zach of his father's prowess as a player.
The United icon said:
The only thing that frustrates me sometimes is that my son never really got to see me play...I have to say to him, "I used to be quicker than Messi". He’s like, "No you didn’t, I’m quicker than you". He just can’t get his head around it. I find myself saying, "Here’s daddy on TV, here’s one of his goals, watch this". He just wanders out the room!
Giggs will be in the Old Trafford dugout on Thursday as United attempt to overturn a 2-0 deficit in their UEFA Europe League last-16 tie with archrivals Liverpool.
