Sunderland to battle Charlton and Blackpool for League One winger
The 25-year-old’s deal with Wigan expires at the end of this month.
The ex-Birmingham City youth Solomon-Otabor made 31 appearances, scoring twice, for Wigan last season.
Meanwhile, George Dobson looks set to leave Sunderland on a permanent basis.
AFC Wimbledon head coach Mark Robinson has revealed that his club have made an offer to try and sign the 23-year-old after a successful loan spell, but believes that they will be outbid by another club.
Dobson made 24 appearances at Wimbledon last season, a key part of their revival as they escaped relegation from the third tier.
That looks to have attracted other suitors for the midfielder, who Sunderland are willing to let go as they restructure their squad.
