Lukaku, who has agreed to a €9 million (£8.24m/$10m) annual contract with Juventus, posted a video on Friday showing the results of a speed test from United’s training, with the Belgian clocking the second highest speed of the session at 36.25kph.
While Portuguese defender Diego Dalot recorded the fastest speed of 36.43kph on the test, his fellow full-back Shaw had the lowest score for all players tested at 31.03kph.
