HITC Sport understands duo are tracking Preston defender Cunningham.
Cunningham has established himself as one of the most consistent defenders in the Championship after impressing in the past three seasons for Preston.
The former Manchester City youngster is entering the final year of his contract at Preston and as yet there has been no new deal agreed at Deepdale.
The news has alerted a number of Cunningham's suitors who are ready to test Preston's resolve to hang onto the left-back this summer.
The Baggies expect to lose a number of their key stars who will not want to drop down into the Championship and the club's scouting staff are already looking at players who have experience of playing in the Championship for next season.
Fulham are also in the market for left-back reinforcements with Matt Targett expected to return to Southampton following his loan spell at Craven Cottage, while speculation continues to surround the long-term future of Ryan Sessegnon with a host of the Premier League's top clubs chasing the teenager's signature.
Preston are keen to keep hold of Cunningham with the Republic of Ireland international a key member of Alex Neil's side, but they are bracing themselves for offers this summer.
