Sunderland have rejected a second bid of £3.5m from Brighton & Hove Albion for midfielder Paddy McNair, according to reports.
The second offer comes only days after the Seagulls tabled a £2m bid for the 23-year-old which was swiftly rebuffed.
According to Sky Sports, Brighton's improved offer of £3.5m was rejected as the club are unwilling to part with McNair for less than £4m.
The Premier League side, however, face competition for the Northern Irishman, as the report also claims an unnamed London club made an offer of £3.75m - which was also knocked back.
