It's been a bizarre transfer window for Sunderland, but then again, when is it ever simple? Sam Allardyce has brought in five new additions to his relegation-threatened squad as they battle against the drop. Will deadline day present any new deals to the Black Cats? German centre back Jan Kirchhoff signed from Bayern Munich for under £1m, while Lorient defender Lamine Kone was snapped up in a £5m deal to reinforce the shaky backline. Veteran 'keeper Steve Harper joined on a free, with striker Dame N'Doye signing on loan, while attacking midfielder Wahbi Khazri represents Sunderland's most expensive - and most exciting - transfer business of the window, with a fee of £9m. There has also been a raft of outgoings in order for Allardyce to free up wages. Steven Fletcher and Jordi Gomez are the two most likely exits from the Stadium of Light today, but it remains to be seen whether a potential suitors are willing to snap either of them up, particularly with Fletcher available on a free transfer in the summer. Will Sunderland strengthen their cause with just hours left in the transfer window? You'd think that they would be browsing the market for a full back on either side, though with the mayhem of deadline day and a wheeler-dealer boss at the helm, anything is possible.
