When David Blatt was appointed Cleveland coach, he fulfilled a dream.
He had an excellent roster with one of the best players in the league, Kyrie Irving, when he had only something to gain.
But one post changed everything, when the best player in the world announced he was coming home.
On the face of it Blatt was supposed to be happy, but the pressure and dealing with LeBron James turned a dream debut season into a big disappointment, and allowing a contract at the end of the season.
So it's true that Mauricio Pochettino's story is not the same as Blatt's, but the Argentine also came to PSG as a respected coach, who did great things in underdog teams (especially at Tottenham), but still with an empty trophy cabinet.
It is true that he has a French Cup, but the relegation to the Champions League and the loss of the championship to the night only increased the pressure on him, and after the great summer of Leonardo and Al-Khalafi, anything but winning the Champions will be considered a failure.
The one who has to connect all this beauty built in Paris - is the coach, who expects a not simple professional challenge.

The first task for him is to build a hierarchy and decide on an array and style.
In the first game of the league, which took place last week, PSG opened with a 4: 4: 2 formation, which probably will not happen against the greats in the Champions League, where a strong midfield is critical.
Messi is used to being part of a dominant team that holds the ball and presses high, a team whose entire parts work for him and allow him to save energy on defense.
With Neymar it worked in Barcelona, but we must not forget the trio that played behind them - probably the biggest ever - and the third attacking player (Luis Suarez), who specializes in pressure and aggression at the front.
Killian Ambape is really not Suarez, and he also comes after a traumatic summer in his terms and contract season.
On the one hand, everyone will want to see the trio (with Neymar) play as much as possible together.
On the other hand, professionally it can be problematic, especially against teams like City, Bayern Munich and Manchester United - pressing and coordinated teams - who can crush PSG in midfield to the extent that the trio do not work properly on defense.

This is where Angel Di Maria and Julian Drexler come into the picture, players who know how to work for the team.
It will be interesting to see if and who the coach will bench to balance the game against the big teams, and also how he will deal with the ego from the bench.
Messi's arrival in Paris may be a dream come true for the players, fans, fantasy fans and FIFA players, but it is precisely for the coach that this could be the beginning of a nightmare.
Even before Messi arrived, Paris with a perfect summer put the strongest team on the continent, at least on paper.
And now that he has been added, everyone is looking forward to a football celebration in every game, with each mishap increasing the pressure on the coach, who is in a position in advance where he mostly has something to lose.
Bottom line, it could end in either a scandal or a festival, and if that were the first option - it would fall first on Pochettino.
