Interesting you should mention some other top attacking midfielders there. Some of the best midfielders ever were not in the same place as Foden at that age.
Playing for the best team in the world. 5 league titles to his name, 4 league cups, 2 FA cups and a Champions league. 130 league appearances in 6 years with 35 league goals. A season where he was unfit for half it and still scored 11 goals. Absolutely incredible.
Rivaldo had only just got to Europe aged 23, he signed for Deportivo from Palmeras.
Ronaldinho was going into his second year at PSG. The previous season he had scored 9 goals in a poor French league, and that year he scored 8 goals. He was no way near world class.
Zidane was still at Bordeaux, he only scored 6 goals that year and the previous year scored 6 too. In fact, he never scored 11 league goals in a season, in his entire career.
Maradona was in his second year in Europe with Barcelona. The previous year, he scored 11 goals, that year, he scored 11 goals. He hadn’t won anything of note at that age.
You could literally keep rattling them off. Very few players are the finished article at 23. Foden is exactly at the development stage he should be at.
You only have to look at him on the ball, the way he glides with it and his intelligence. That’s a very special young man. If he kicks it up a few levels with a good run in midfield, as one of our most important players. He could become world class pretty quickly.
