I mean for sure, Mbappe is the best young talent in the world at the moment, and over past few years too, I don’t think anyone will disagree to that - he is simply the best young player in the world.
But question is, can Rashford match that level? Base on their performance over past few seasons, there’s no comparison, which is quite obvious.
But how about this season? Let’s see:
Rashford 19-20
League: 14 goals in 22 games
Europe (EL): 4 goals in 3 games
Club overall: 19 goals in 31 games
International (2019): 4 goals in 7 games
Mbappe 19-20
League: 18 goals in 20 games
Europe (CL): 5 goals in 7 games
Club overall: 30 goals in 33 games
International (2019): 3 goals in 6 games
Performance wise both Rashford and Mbappe has been impressive this season.
But stat wise we can see Mbappe is still comfortably ahead, but the gap is getting smaller for sure.
But bear in mind majority of the goals Mbappe scored are in French league against weaker opponents, and in a very dominant side too (PSG regularly beat their opponents by at least few goals In French league, even without playing Neymar, Mbappe etc)
So in view of above, the gap between Mbappe and Rashford, could actually be smaller this season.
Now let’s look at some examples of players stats in French and English league in the past, in terms of their best season in respective league within 1-2 years apart, to give a more accurate comparison:
Ibrahimović
15-16: 38 goals in 31 games in French league
16-17: 17 goals in 28 games in English league
Depay
15-16: 2 goals in 29 games in English league
17-18: 19 goals in 36 games in French league
Lacazette
16-17: 28 goals in 30 games in French league
17-18: 14 goals in 32 games in English league
As you can see, it’s quite common for same players to score double their amounts of goals in French league as compared to English league. The standard between the two leagues are definitely not the same.
So by the same logic, could Mbappe still score 30 goals in 33 games for us this season in England? I’d doubt it, I think maybe he could score around 20 goals, which is similar to what Rashford did. But we could never know for sure.
Now let’s look at the stats of other top players in England this season:
Rashford: 19 goals in 31 games
Salah: 20 goals in 40 games
Kane: 17 goals in 25 games
Agüero: 23 goals in 30 games
Sterling: 20 goals in 39 games
Rashford is already among the top in England this season, even comparing with all these world class players. So I do really think Rashford is currently playing very near to Mbappe level, if not at the same level already.
