The Premier League must take heed of Mauricio Pochettino's words after the Tottenham manager slammed a lack of professionalism from rival clubs.
Pochettino was furious after a number of other managers publicly stated that they wanted Leicester - and therefore, not Spurs - to win the title.
Understandably, as everyone's favourite underdogs, Leicester received an unprecedented level of support, but the White Hart Lane boss made it clear that he felt some comments bordered on unprofessional.

Speaking to Sky Sports, he said:
"Maybe in the next few meetings of the Premier League, the managers and also the staff, we need to say that in future we must be careful with all these comments in public.
"In football, our responsibility is to be professional. When you are professional, you do not give your personal opinion."
He was particularly unhappy after Chelsea pair Cesc Fabregas and Eden Hazard both admitted they hated the idea of Tottenham winning the league, despite still having Spurs and Leicester to play at the time of the remarks. And while they achieved their goal of handing Leicester the title with a 2-2 draw, their remarks may well have played a role in the 'Battle of Stamford Bridge', which escalated into a vicious exchange.
In some quarters, Pochettino's anger has been readily dismissed as a case of sour grapes.
However, had the title race gone to the final day and been dependent on Chelsea's game with Leicester, it could have led to some serious questions.
Of course, it is unlikely that there will be a situation next season which pits a massive underdog against a relatively big club, but the Premier League should lay out some guidelines nonetheless.
After all, several clubs have been fined in the past for failing to put out a competitive side. Mick McCarthy's Wolves were fined for making 10 changes to the side that faced Manchester United in 2010. By those standards, the Premier League should be very concerned about Chelsea's hints that they would raise their game against Spurs, but not Leicester.
The Premier League prides itself on its competitive nature, but that faces being ridiculed if a repeat of the last fortnight's comments are allowed to happen again.
