West Brom are lining up a swoop for Valencia forward Jonas, Sky Sports understands.
West Brom boss Pepe Mel is on the lookout for attacking reinforcements to help lift his side away from the Premier League drop zone.
Former Real Betis boss Mel is well aware of the talents of Jonas having come up against the forward during his time working in La Liga.
The Brazil international has impressed at Valencia since arriving from Gremio in 2010 and is being tipped to be included in his country's World Cup squad for this summer's finals.
Jonas, who attracted interest from Tottenham, Everton and West Ham last season, has scored nine goals in 18 appearances for Los Che this term.
The Baggies are hoping to steal a march on their Premier League rivals by luring the 29-year-old to the Hawthons before the transfer window closes on Friday.
A number of other Premier League clubs are thought to be tracking Jonas, but should West Brom land Jonas it would be a major boost for Mel as he looks steer the club to safety in the Premier League.
