Former Tottenham and Manchester City defender Vedran Corluka is said to be upset at the wages being earned by a player who once played for Portsmouth, Chelsea and Arsenal.
Remember Vedran Corluka? He is now playing in Russia with Lokomotiv Moscow.
After being bought by Spurs from Manchester City for £8.5 million in 2008, he fell out of favour with Harry Redknapp in the manager's last season there, and Andre Villas-Boas moved him onto the Russians early in his tenure.
It was a lucrative deal for the Croatian international, for after paying £6.6 million for his services - he became Lokomotiv's highest paid player.
That was until this summer, when Lokomotiv brought in two new fresh faces earning more than him.
These were Moroccan international Moubarak Boussoufa, and former Premier League face Lassana Diarra.
Both signed at the end of the window in the Anzhi Makhakhala firesale and have helped take them to second in the table - with another Spurs player Roman Pavlyuchenko leading the attack, scoring twice in the last two games.
On the pitch they have certainly had a good effect, with Diarra formerly donning the shirts of Chelsea and Arsenal briefly, most well-known for spells with Portsmouth and Real Madrid.
Off the pitch there appears to be a little disquiet, with Corluka said to be jealous of their high wages and wanting an increase.
Russian newspaper Izvestia reports that despite Corluka's contract expiring in 2016, he is angling for a January pay rise to match the level of his new teammates.
If he does not get it, the paper add, there has been interest from abroad in the right-back, and he could seek to move on.
Should the 27-year-old's familiar face present itself in the Premier League in a January transfer window for a club searching for a new right-back, it will be because the green-eyed monster got the better of him.
What do you remember about Corluka's time in the Premier League?
