Zirkzee wanted by Serie A duo amid uncertainty over his future under Amorim

Joshua Zirkzee is attracting interest from Juventus and Napoli but will fight for his Manchester United future.

The Holland international started his career at Old Trafford, following a £36.5million arrival from Bologna in the summer, with a bang by scoring on his debut in a 1-0 win over Fulham on the opening day of the season.

Although he has continued to play regularly, the 23-year-old's season has stuttered since then, culminating in his 33rd-minute substitution against Newcastle on Monday night.

Zirkzee's stock remains high in Italy, with Juve and Napoli revisiting their interest in the striker amid hope from the Serie A sides that there may be an opportunity to sign the forward due to uncertainty over his position in Ruben Amorim's plans.

Both clubs were keen on Zirkzee, who has scored four goals this season, in the summer but were beaten to his signing by United.

And Mail Sport has learned that both clubs are manoeuvring themselves into a position to strike for Zirkzee should it emerge he can leave.

Zirkzee is believed to be aware of the interest but is fully focused on his season with United and has no desire to leave as he concentrates on playing a role in moving the team up the table.

His first-half substitution against the Magpies arrived as an obvious blow but has not dampened his determination to succeed.

United head coach Amorim, in explaining his decision to replace Zirkzee in the 33rd minute, explained: 'Josh is a really good lad. We will support him and keep going. It was really tough for me to do that, but I've spoken to Josh as it was important to express the message. We needed Josh to go out, for the team.

'The player is suffering and I was there myself a few years ago. I felt he and the team were suffering during the game and we needed another midfielder. It was tough on me to do that and I've talked with Josh about that because it's important to relay the message.'

Monday's defeat left United with just 22 points at the midway point of their Premier League campaign.

The Red Devils currently sit 14th in the table - 13 points off the top four and just seven clear of the relegation zone.
