The Bhoys boss is prone to reunions. Could he organise another at Parkhead?
If recent reports are anything to go by, Brendan Rodgers is keen to add a winger to his newly-acquired Celtic squad.
Both players are linked to Rodgers, who gave Robson-Kanu his senior debut at Reading and was Edwards' manager at Swansea City.

The Northern Irishman, of course, is prone to a reunion: He signed Watford's Jobi McAnuff for Reading having made the move himself, took former Royals midfielder Gylfi Sigurdsson to Swansea and is responsible for Joe Allen's transfer from the Liberty Stadium to Liverpool.
So could he line up another in the shape of Nathan Dyer? The 28-year-old was a key member of Rodgers' Swansea side, which gained promotion via the Championship play-offs and established itself as a regular top-half contender in the Premier League.

However, after a season on loan at Leicester City, in which he appeared 13 times en route to an unlikely league title, Dyer returns to Swansea both out of favour and out of contract in 12 months' time - which could spell a bargain for Celtic.
With nearly 150 appearances in the English Premier League, European experience and pace to burn, Dyer, and not Robson-Kanu or Edwards, would be the perfect Rodgers reunion.
