This will be unpopular but I don’t really agree except for the driven bit.I compare him to Defoe in terms of ability but Defoe was better and more driven.
Rashford - 1 goal every 3.21 PL games
Defoe - 1 every 3.03. His spurs average is pretty much identical
But Defoe only had 30 assists in 496 PL games. Rashford already has 47 in 267.
The truth is they aren’t really comparable as players - Defoe was much more of an out and out striker. But when he’s focused Rashford has just produced more - his 4 best seasons for goal involvements in the PL are 26, 22, 22 and 18, and he’s still only 26. Defoe only has one season over 17 (when he scored 18 and assisted 5 for us in 2009/10, by far his best season).
Defoe was a great guy who gave everything and Rashford seems to be wasting his talent somewhat, but his ceiling is higher
