West Bromwich Albion goalkeeper Sam Johnstone has posted a video on social media that is sure to amuse the club's fans.

The 25-year-old posted this video on his personal Instagram account earlier this afternoon, on what is International Happiness Day.

The footage shows the Baggies goalkeeper laughing uncontrollably during a behind-the-scenes interview with the club.

The Verdict:

Johnstone clearly has a good sense of humour and it is amusing to see the player making fun of himself with his latest social media post.

The goalkeeper has proved himself to be an important player for West Brom since arriving at the Hawthorns from Manchester United in the summer.

He has made 38 appearances for the club so far this campaign, starting every game in the Championship and has managed to keep seven clean sheets in the competition.

His form over the next few weeks will be crucial as the Baggies, who are currently without a permanent manager, look to cement their position in the play-offs.

Johnstone has kept clean sheets in both of his last two matches and West Brom fans will be hoping that he can continue this form ahead of the final few weeks of the season, starting with the home game against Birmingham City a week on Friday.

Albion supporters will be hoping that the goalkeeper can show better composure against the Blues than he did in this video, but for now, it is nice to see the player having a laugh.
