Baggies boss Robson has already boosted his attack this summer by signing Diomansy Kamara, however, he wants yet another striker on board before the start of the season and has made Ellington his top priority.
Robson is understood to have plenty of money left to spend, and with Ellington having just a year left on his current contract and seemingly unwilling to extend that deal, Robson is likely to make a bid around £1.5m.
