Antoine Griezmann is linked with a switch to Barcelona, but Gabi hopes the forward remains at Atletico Madrid.
Griezmann was the hero in Lyon on Wednesday, scoring a brace to guide Atletico to a 3-0 win over Marseille in the final.
Gabi said the 27-year-old’s team-mates had already tried to convince Griezmann to stay and he hopes the trophy helps.
“Let’s hope today’s performance convinces him to stay there.”
“Otherwise he would be in another team now.”
