Earlier his summer, Coman announced that he was leaving PSG on a free transfer to join Italian champions Juventus on a long term deal, much to the chagrin of the Parisians, having been seen as one of the brightest prospects to emerge from the French side in years.
“The problem was the contractual situation,” Blanc told Tuttosport during his sides pre-season tour of Asia.
“Coman could not leave for another French side but he was free to move abroad. The Italians [Juventus] were clever, saw that we were not in a position of strength and took advantage of the situation.”
Another young superstar in the making, Adrien Rabiot, could be set to tread a similar path this summer with Juventus, Roma and Inter heavily linked with bids for the French under-21 international midfielder as his contract expires in 2015.
“Rabiot is likely to be the same thing; we are not in a position of strength regarding his contract.”
PSG are believed to be open to a sale for Rabiot this summer so as not to lose their two brightest prospects in the space of a few months, but are believed to be insisting on including a buy back clause in any deal at the moment.
