The Black Cats drew 1-1 with Coventry City at the Stadium of Light on the opening day of the season. Alex Neil’s side then backed that up with a come-from-behind 3-2 win over Bristol City at Ashton Gate.
Sunderland took the lead inside four minutes when debutant Ellis Simms, on loan from Everton, opened the scoring. The hosts drew level six minutes later through Andi Weimann, before Chris Martin put the Robins ahead.
Simms then added a second, allowing Ross Stewart to head home the winner 18 minutes from time. The Wearsiders remain active in the transfer market and are eyeing additions before the window closes.
Here, we take a look at some of the free agents released by Premier League clubs this summer that are available to Sunderland and their rivals before the window slams shut next month:
