It took Romelu Lukaku a matter of seconds to fire Manchester United into the lead in Wednesday's Premier League clash with Newcastle United after coming on from the bench. The Belgian striker, as a result, grabbed his second goal in two games under Ole Gunnar Solskjaer.

Lukaku, who is yet to start a game under the new boss, was introduced into the fray to replace Anthony Martial inside the 63rd minute. A free-kick which was won by his side prior to his involvement was subsequently executed by Marcus Rashford from about 28-yards out.

However, the power in the 21-year-old forward's strike made it difficult for Newcastle's Dubravka to hold onto the ball, spilling it right into the path of Lukaku. The ex-Everton striker simply finished it off by poking the ball into the net. Watch the goal below:

Fellow substitute Alexis Sanchez marked his return to action after a lengthy layoff by assisting Marcus Rashford to consolidate Manchester United's lead in the 80th-minute. Despite still sitting sixth on the Premier League log, the Red Devils are now six points short of a top-four spot.
