"Cattermole is keen to leave the club after a difficult few seasons for both club and player, but with the 30-year-old previously signing a deal which could see him stay until 2021 - a contract agreed with then CEO Margaret Bryne - it may be a more difficult situation than the Rodwell one, due to the former Manchester City man only have one-year remaining on his deal.
With the player and his agent - who, coincidentally, is Margaret Byrne - keen on getting every penny he is entitled to over the length of his contract, discussions that will see the player leave the Stadium of Light may be slow-going."
