Newcastle and Norwich keen on Sporting ace
The Canaries have been tracking the Dutchman for some time, and are believed to have made an approach for his services during January.
Chris Hughton has been linked with a summer move for the 24-year-old, but he may face competition from Newcastle.
The Tyne club are reportedly monitoring the striker, who has hit 22 goals since the start of last season, as they look to strengthen their squad.
Sporting are in a state of financial turmoil, with spiraling debts likely to force sales of star players.
Van Wolfswinkel is one of their most valuable assets, and the Portuguese giants are said to be willing to accept in the region of £10m for his signature.
But, as well as the Premier League pair, teams from Eastern Europe, including Dynamo Kiev, are keen on ex-Utrecht man.
A striker is believed to Norwich’s main priority in the transfer market, with the East Anglians managing just 28 goals this season, the third fewest in the division.
Newcastle are also keen for striking reinforcements, after watching their January move for Loic Remy fall through thanks to QPR’s spending power.
