Yes the stats are correct, since 1st Jan 2020 so the last two years as that was what I was quoting.
Lukaku is a bizarre comparison since he plays a completely different position and role but yes, during the same timeframe he has scored 50 goals and made 17 assists.
If you would like further context, Lukaku has played a total of 7481 minutes in that time and averages a G/A every 112 minutes, Rashford has played 6456 minutes and averages a G/A every 122 minutes.
So essentially, despite being a centre forward rather than a winger, playing the majority of his football in a considerably weaker league, playing for a better side in that weaker league, not playing the vast majority of last season clearly injured and supposedly being in his prime years, Lukaku still only just edges Rashford for goal involvements which is all rather comical given he's supposedly worth £90m and this forum would have you believe Rashford is useless.
