Arsene Wenger was angry when he found out the Tottenham and England striker slipped through the net, while City thought United ace Rashford was too small
Kylian Mbappe once had a trial at Chelsea before he decided to join Monaco’s youth team.
It was in the south of France instead of south west London where he thought he had the best chance of developing his talent.
“I was still young back then, maybe 10 or 11. I went to London and spent just under a week over there. I trained at Chelsea and we played a friendly match against Charlton,” he has said.
“We won 6-0 or 7-0. I played upfront, but I don’t think I scored. It was great – it was my first experience abroad and a chance for me to see what the game was like in England.”
He’s still only 19, but has already secured a £165m switch to Paris Saint-Germain and won the World Cup with France.
