After leaving in 2023, Robinson has been forthcoming about his hits and misses as a scout.
He stated that he passed up on the opportunity to sign Dele Alli, Joe Gomez and Jadon Sancho.
Robinson told Rising Ballers: "This is a bit embarrassing for me.
I was watching an England game on TV and one of my sons phoned me up and said: 'You do realize you said no to three of these players who are playing for England?'
The players were: Dele Alli, who I saw when he was playing first-team football for MK Dons at 17 and I didn't feel he was better than we already had at Chelsea in Ruben Loftus-Cheek and Lewis Baker.
"Was I right? I was at the time, I believe. Dele was a different shape, he was heavier, more of a central midfield player.
"He went to Spurs and blossomed as a player. Lots of other scouts at Chelsea came to the same conclusion, so it wasn't just me.
"Joe Gomez, when he was at Charlton at 16 or 17. I thought he was a great athlete, I didn't think he was a great footballer.
"He's gone on and done OK, hasn't he? And Jadon Sancho. I saw Jadon when he was an under-14 playing as a striker for Watford.
"I thought he was all right, just OK. He signed for Manchester City almost straight after and we knew City were interested. He became a winger there and the player he later became for Dortmund."
