Disasi is the winter saga that many didn't realise they needed.

The defender initially wanted to stay and fight for his place - as reported on BBC Sport earlier this month - but he was told in no uncertain terms that it would be better to leave Chelsea.

Both Aston Villa and Tottenham emerged as suitors on deadline but Spurs quickly went cold on signing the France international after feeling he didn't want to join.

His agents then, seemingly out of nowhere, appeared to convince Disasi that Spurs was a better but they ultimately lost out to Villa.

What actually went on behind the scenes a player caught between the two sides arguing their case - with Chelsea receiving similar terms regardless of where he went - and not massively influential despite simply wanting him out.

Crystal Palace

League One Wigan Athletic have signed Oxford United winger Owen Dale on loan until the end of the season.
