Willem II striker Fran Sol is being scouted by Old Firm rivals Celtic and Rangers, according to a report.

The 26-year-old, who started his career with Real Madrid before spells with Villarreal and Willem, has struck 12 goals in 16 Eredivisie outings this season.

Sol's form has seen him touted as a possible target for English Premier League sides Cardiff City, Burnley and Huddersfield Town, while Championship duo Derby County and Swansea City may also be in the running for his signature.

The Mirror reports that the Spaniard is now being tracked by Celtic and Rangers ahead of the January window, with both sides sending scouts to watch him up close.

Willem are expected to take up the option of a one-year extension in Sol's contract, which is currently due to expire next summer, but they may still cash in if the price is right for a player boasting 45 goals in 84 games since joining in 2016.
