Jose Mourinho is arguably the most outspoken manager in the Premier League. But while it is often entertaining, it can also prove to be rather troublesome.
Whether it is criticising a fellow manager, player or incident within a game; Mourinho has never been known to shy away from making his feelings known in public.
It may make for great viewing, but the Portuguese certainly doesn't do himself any favours, at times.

But while Mourinho has had the FA to answer to in the past, he has received criticism in recent days, following the Manchester United boss' comments at the weekend.
Following last Sunday's 3-1 victory over Swansea City, the 53-year-old slammed Luke Shaw and Chris Smalling - questioning their commitment and "bravery" - saying: "For the team, you have to do anything.

"There is a difference between the brave, who want to play at any cost, and the ones for whom a little pain can make a difference.
"If I were to speak with the many great football people of this team, they will say they played many times without being 100%.
"We have players on the pitch with problems. In every sport, how many times do you play and you're not 100%?"
However, as per the Daily Mail, it appears that the Manchester United boss has been left rather embarrassed, with Smalling set to be out until after Christmas - having suffered a broken toe.
The United defender hasn't feature for the Red Devils since their 4-0 thrashing at the hands of Mourinho's former club, Chelsea, at Stamford Bridge last month, when the 26-year-old was required by the Portuguese to have two injections in his foot, to get him through the match.
Mourinho's questioning of Smalling's decision to rule himself out of the game against Swansea now has proved to be somewhat unfair, and that the England international was clearly in no state to feature against the Swans.
While Smalling could return potentially before Christmas, he is certain miss key fixtures against Arsenal, Everton, Tottenham and the League Cup quarter-final against West Ham, in a packed seven-game period.
Mourinho's defensive nightmare
And, on top of Mourinho being left to rue his decision not to keep his opinion on both Smalling and Shaw behind closed doors, the injury blow couldn't have come at a worse time for the Portuguese.
Eric Bailly suffered knee ligament damage, ruling the Ivorian out for two months, last month, while Phil Jones' return from a long-term injury lay-off means he will be reliant on the 24-year-old getting back to top form as soon as possible.
Mourinho is already thought to be considering defensive reinforcements during the January transfer window, with Atletico Madrid's highly-rated Jose Gimenez, Benfica's Victor Lindelof and former player Michael Keane all on his transfer list.
Now with the Red Devils set to face a crucial run of fixtures without one of their key centre-backs, who clearly was not fit enough to face Chelsea, the next month could leave Mourinho wanting to eat his own words.
