Despite both managers insisting they will be civil towards one another, questions continue to be asked of Jose Mourinho and Pep Guardiola's relationship.
The revered pair clashed on a number of occasions whilst managing Real Madrid and Barcelona respectively, and it's widely believed they will come to blows once again in the upcoming Premier League season.

For Mourinho, though, questions regarding his Spanish adversary are pointless.
So much so that when a reporter asked whether he will acknowledge Guardiola when the two reunite, the Portuguese snapped.
According to Goal, he said: "To qualify the question I would use some impolite words.
"Of course I'll shake his hand. I don't understand the question to Guardiola and I don't understand the question to myself.
"We worked together at Barcelona and we worked against each other in Spain. I don't see the reason for the question."
Mourinho was said to be visibly agitated as he conducted a pitchside interview at Beijing’s National Stadium, after the press room was deemed too small and too hot.
Regarding his side's game against City on Monday, he added: "The pitch is very bad and the condition of my players is more important than results.
"We cannot just run away and disappear and not play, so we have to play and try to be lucky.
"Normally when we say lucky we say lucky because we want a good result. The result I want tomorrow is to go home without injuries.
"Manchester City have all of their players, we have six, seven or eight, who played in the Euros. What I want is to get back to Manchester and train with the full group.
"Travelling to China is good for the fans and for the commercial side of things. We have a good group, we have a good spirit and we cope with it. Tomorrow is the last day and then it is over."
Mourinho and co. will be relieved when their tour of China concludes, especially so after a plane carrying the likes of Memphis Depay was forced to land in Tianjin on Saturday night, 70 miles away from Beijing.
