I don't know what "this" is, but the fact that he managed to do some good things once or twice a season is neither here nor there really. He never moved towards the ball when it was passed to him, so if his defender was alert enough, the ball wouldn't even reach him. That's rule 1 of hold-up play and Lukaku just couldn't do it, while DCL does it all the time.
And don't get me started on the number of times the ball just bounced five yards away off his foot.
Of course all this was more than compensated for by his finishing ability, which DCL lacks, but let's not start rewriting history.
It was frustrating that he was inconsistent with it but let’s not make out that he was Beckford-esque.
I wouldn’t say that out hold up play has improved at all.
