Arsenal boss Mikel Arteta insists Joe Willock will not be sold this summer.
The 21-year-old has scored seven goals in 10 Premier League starts after joining Newcastle on loan in January.
Manager Steve Bruce said Newcastle "would love" to sign Willock in the summer, but Arteta is not looking to sell the England Under-21 international or send him back out on loan.
"He has a contract and is going to be here, that's for sure," said Arteta.
"I am really happy things have gone so well for him because of the potential Joe has. It was great for him to go away and have a different experience.
"He has grabbed that opportunity in a really positive and remarkable way, and he will be back with us. We will have those conversations with him and plan the next few years with him."
Willock, who is under contract to 2023, scored three goals in the Europa League for Arsenal this term before joining Newcastle until the end of the season.
He scored on his debut, a 3-2 win over Southampton in February, before scoring in his last six games, helping the Magpies secure their top-flight status for another season.
"He got the responsibility and the task to go to Newcastle to help them go where they want," Spaniard Arteta added. "I spoke with the coaching staff and they are extremely happy because he was a key part of getting the objective they have. That's a real positive for him."
