Newcastle head coach Steve Bruce has vowed to test Arsenal's resolve to hang on to midfielder Joe Willock, but Mikel Arteta has insisted the young midfielder is not for sale.

Bruce admitted that Willock's exploits at St James' Park have served as a "double-edged sword".

The 21-year-old midfielder became the youngest man to score in six consecutive Premier League games in midweek to further enhance his loan spell on Tyneside, although Arteta indicated that the Magpies' hopes of securing his services on a longer-term basis would be in vain.

Bruce said: "We always said that it was a double-edged sword, and we have to respect that he is Arsenal's player.

"We'll see over the summer whether we can test their resolve, but as I said from day one, I'd like to thank Mikel and Steve Round and the football side of it because they were instrumental in getting me him and letting us borrow him for a few months.

"It's been great. He's been great for us, he's been great for Newcastle. He's done well and propelled himself into - when I see what he's done in the last few weeks and the names who have scored six in six, it's quite remarkable, so well done to Joe.

"Let's see. As I've said many, many times now, I've got total respect. Let's not disrespect Arsenal, he is their player."

Arteta however insists he has no plans to allow Willock to leave Arsenal.

After bagging the winner in Wednesday's 1-0 win over Sheffield United, Willock was hopeful "there's more to continue in the future", but Arteta seemed to close the door on that prospect.

Asked whether Willock will still be an Arsenal player next season, Arteta said: "For sure because he's got a contract and he's going to be here. That's for sure.

"I'm really happy things have gone so well for him because of the potential Joe had. I think 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. He will be back with us, we will have those conversations with him and plan the next few years for him."
