Eventually, the superstar signed a new deal with a stunning reported release clause of €700 million.
Sampaoli has a wealth of attacking options having called up Mauro Icardi, Paulo Dybala and Sergio Aguero alongside Messi last time out, but the Barcelona star feels Higuain is crucial to the national team.
However, he has conceded that his willingness to return to his homeland will depend on the state of the country at the time. "Simply, a greeting and the usual respect, that's all", concluded Messi.

"I know there have been a lot of controversy [regarding Arthur] but I have only heard it from the distance.
He has to be [in the team] because he is vital, he is one of the best forwards in the world and he always shows it".

Higuain has nine goals and three assists in 13 Serie A starts for Juventus, who are in third place in the table in Italy, two points behind leaders Inter.
"I think it's the last opportunity for this group".
