Jamie Vardy didn't have the best of afternoons yesterday.
The England striker played just 45 minutes of Leicester City's disappointing 4-0 defeat to Manchester United on Saturday afternoon, after being subbed off at half time with the game seemingly already out of reach.
But, whilst he didn't last the full 90, Vardy did still find time to vent his frustration out on the pitch. Unfortunately for Mike Dean, it was the Premier League referee who came in for some foul-mouthed abuse at one stage on Saturday.
The Leicester forward has already has a bit of a reputation for berating match officials after launching a torrent of abuse at Jon Moss following his red card against West Ham last season.
And, judging by the video below, he was at it again against United yesterday...
WARNING: Bad language
It doesn't take an expert lip reader to work out what Vardy was saying to Dean but, fortunately for the striker, it appears the experienced referee didn't hear the abuse as Vardy escaped without a card of either colour.
Whilst the 29-year-old has enjoyed a near meteoric rise to stardom in recent years he hasn't done so without some controversy.
Alongside a tendency to lose his head with officials, Vardy has also faced criticism for diving as well as unsavoury incidents off the field - including one claim that of directing racist comments at a Japanese man at a casino back in August 2015.
Yesterday's outburst wasn't at that level, but Leicester fans will be hoping Vardy tones things down moving forward as they can ill afford to be without their star man through suspension.
Six games into the new season, Claudio Ranieri's men find themselves in 11th place with seven points and three defeats to their name.
With Champions League football to contend with too this season, Vardy will once again be critical to the reigning Premier League champions chances of competing this season.
