Arsenal have scheduled talks with Sporting CP over a deal for Joelson Fernandes.
The winger, 17, signed a three-year deal at the Primeira Liga side in February 2019.
The Sun says with his contract expiring at the end of the 2021-22 season, Sporting have been scrambled to tie Fernandes down to a new deal.
The club thought they had convinced him to stay last month.
But the deal fell apart over the finer details, such as a disagreement over the release clause fee.
Now, Sporting appear resigned to losing their star youngster.
And they could sell him as cheaply as £18million rather than allow him to see out his contract and leave on a free.
