Following Sunderland's 3-1 defeat to Coventry, concerns are growing over the Black Cats' form, with fan Eleanor McCabe describing the performance as "appalling".

Sunderland are now winless in seven Premier League games and have failed to keep a clean sheet away from home all season.

Despite the poor run, manager Regis le Bris is expected to be given more time, with club sources believing he can turn things around.

The Frenchman led Sunderland to promotion before guiding them to seventh place last season and a historic Europa League spot.

With Dinamo Zagreb up next on Thursday, followed by Chelsea on Sunday, pressure is mounting.

So what's going wrong at Sunderland?
