Marcus Rashford appeared to take a swipe at Manchester United following his inclusion in the England squad.
The forward posted on Instagram after being announced in the Three Lions 26-man setup, saying: "Special thanks to Unai (Emery), Hansi (Flick), Thomas (Tuchel), Aston Villa, Barcelona & England for believing in me when things got tough."
Rashford concluded the message with a red heart, notably excluding United from his message.
The 28-year-old is pursuing a permanent deal at Barcelona, who are strapped for cash and trying to lower his price.
United are insisting that the £26million agreed in the initial loan-to-buy deal is paid.
Rashford recorded 14 goals and 14 assists across all competitions this season, impressing German coach Flick.
The Englishman still have a couple of years left on his five-year deal, which earns him £325,000 a week.
He has spent half of his new contract on loan, first at Emery's Aston Villa before heading overseas to Spain.
