Celtic and Newcastle United are following Costa Rica ace Bryan Ruiz.
The Scottish Sun says Celtic had a scout in the stand on Sunday to watch the striker score for Belgian side AA Gent against Zulte Waregem.
The 6ft 1in star is attracting attention from Newcastle and clubs in Holland, Italy, Belgium, and Greece after netting eight times this season.
Wigan Athletic boss Steve Bruce has also been told to take a close look at Ruiz, who said: "When an attractive offer comes in, I can move on at the end of this season."
