Arsenal fans will have been interested observers tonight as Olympiakos hosted Manchester United in a Champions League last 16 first-leg tie, but could not have predicted the impact their loan starlet would have on proceedings.
Campbell took centre-stage with the Greek champions already a goal to the good, picking up the ball around 30 yards from goal before stepping past Michael Carrick and sending a brilliant curling drive towards goal.
The precise strike dropped perfectly inside the near post to render David de Gea's efforts redundant despite a strong dive towards the corner, making his mark on Europe's biggest stage in some style.
Luckily for everyone but perhaps United fans the goal was quickly captured online, which means Gunners fans can see just what the Costa Rica international is capable of by checking out the video at the top of the page.
Arsenal supporters, do you think Campbell should be brought back to compete for a starting spot next season? Have your say by commenting at the bottom of the page!
