Liverpool FC have released a hilarious video showing star players Philippe Coutinho, Raheem Sterling, Lazar Markovic and Jordon Ibe attempt to take penalties while dizzy.

The Redmen TV and Vauxhall, the official car sponsor of Liverpool FC, filmed the players taking part in the Dizzy Pens Challenge at the club's Melwood training ground upon returning for pre-season training. Each player had to run round in a circle a number of times before trying to take a penalty.

Coutinho and Markovic both failed to find the target, while Raheem Sterling could only hit a weak shot straight into the path of the goalkeeper. Young winger Ibe was the only one to have success, managing to score at the first time of asking.

Liverpool begin their pre-season calendar against the Thai All Stars in Bangkok on 14 July. Their first Premier League match of the 2015-16 season will be away to Stoke City, who they lost 6-1 to in the final game of last season.
