Sunderland are keeping tabs on Freiburg striker Papiss Cisse's situation.
The Mirror says Sunderland are also chasing Senegalese striker Papiss Cisse but German side Freiburg want a big fee although that may come down during the window - and as they face a possible relegation.
Newcastle United could also be in for Cisse after a deal for Sochaux's Modibo Maiga collapsed due to a failed medical.
