Im prepared to get slated for this, but honestly I dont rate lukaku right now... and would put Jones in a similar (note I said similar and not "the same") group as Lukaku's recent performances.
Physical similarities aside, it's obvious RM likes a big fukkin battering ram as his centre forward. Lukaku has that in spades, but has looked lazy or off the pace since his first 10 appearances where he was obviously looking to make an impression. Lukaku is a better finisher, and better technically... but for the role he serves right now Jones could deffo do a similar, if less elegant, job should lukaku get any injuries.
Not saying Jones is as good or anything like that, but for the role they play and measured against Lukakus current "not-so-keen-to-impress form" a million would get us a reasonable alternative to the end of the season.
I really hope it wont happen, but for a million I won't protest too much. We are always complaining about depth in the squad, and sure Jones is not "quality" depth, but you know he would be useful on occasion as long as his 'tude doesnt affect the squad.
If you watch Lukaku he makes reallt good runs which occupy the defenders. He is contributing even when it goes unnoticed. Jones just stands around.
