Barcelona were allegedly left angry with Paris Saint-Germain over their pursuit of Lionel Messi, a wantaway attacker.
The Catalan giants believe that PSG are trying to play mind games with Messi, according to Sport.
Both PSG manager Mauricio Pochettino and sports director Leonardo spoke about Messi’s possibility of trading in the French capital.
The remarks have reportedly left Barcelona seething. Such remarks, they feel, have violated a code of honour between the two clubs.
