(Reuters) - Sunderland are finding it difficult to compete financially with their Premier League rivals in the transfer window, manager David Moyes has said, as he aims to bolster his fragile squad in search of their first Premier League win.
Atletico Madrid defender Javier Manquillo, Barnsley centre back Alfie Mawson and midfielder Yann M'Vila, who spent the last season on loan with Sunderland, have all been linked by British media over a potential move to the Stadium of Light.
