While the French international is only in the second year of his five-year deal, his low release clause of €60 million has only served to increase speculation about him leaving Camp Nou this year.
So far, Umtiti has remained tight-lipped over his future but responded to growing rumours by kissing the Barca badge after scoring against Roma.
According to Diario Sport, negotiations have slowed down between Umtiti’s agent – who is also his brother, after demands of a higher wage – which would place him among the second tier of earners with Sergio Busquets and Pique.
Speaking about the situation, Bartomeu told Cadena Ser: “Umtiti is very important, he knows that, the fans know that.”
“He’s only in the second year of his contract but our desire is for him to renew his deal.
“But, as directors, we have to make sure [players’ wages] are within the salary structure to remain a competitive and sustainable club.”
Speculation has long gathered that the France star will leave the Spanish capital for Catalan giants Barcelona in the summer.
However, after scoring in the 1-1 draw with Arsenal in Atleti’s Europa League semi-final clash, the 27-year-old revealed his representatives are discussing his future plans.
Speaking to COPE after the match at the Emirates Stadium, Griezmann said: “If I’m going to continue at Atletico, I don’t know, we’ll see.
“We’re talking to the club to see what can be done.”
While Griezmann did not shed any light on where his future may lie, the statement does indicate a resolution will be reached in the near future.
Griezmann’s goalscoring exploits have seen him thrust into the limelight as one of Europe’s hottest properties and he further enhanced his reputation with the crucial equaliser on Thursday.
“In the goal I arrived in the area tired after the run I had made, but I was able to score. We needed that goal,” he added.
“Am I important? [Jan] Oblak is important, [Diego] Godin is important, Gabi when he entered the pitch was important… all the players are important.”
Though the summer transfer window is still a couple of months away, that hasn’t stopped the rumours of players potentially being on the move.
