This is honestly pretty cringe from the Inter twitter account. If I was the player, I'd be pretty pissed they even acknowledged it. If anything it just makes the claims more legitimate. Showing him pulling out an impressive first touch doesn't automatically erase all the horrendous first touches we've seen from him. We still remember that. It also means nothing in isolation, you could pull up a video of a Sunday League footballer pulling that off, but that doesn't mean his first touch doesn't put the ball out for a throw in 9 times out of 10.
Anyway, we know what we had with Lukaku. That video is an exception to the norm. If he pulled off basic first touches that were half as impressive as that consistently, then there would be nothing to say.
