And while there may be plenty more movement before the season opener with Oxford United, fans have offered their take on what the Black Cats’ strongest line-up currently looks like. Scroll down and click through the pages to see the team they believe is the best at Ross’ disposal - with some big names missing out:
5. RW: Duncan Watmore
Another area with its fair share of competition, but 43% of supporters believe fit-again Watmore is the sensible choice on the right flank. Photo: Frank Reid
6. AM: Chris Maguire
Impressive after his return from injury towards the end of the season, where he largely operated behind the striker, 60% of fans want to see Maguire handed a similar role in the 2019/20 campaign. Photo: Frank Reid
7. ST: Will Grigg
While he didn't hit the heights hoped for after his January signing, 66% of supporters still believe Grigg is the Black Cats' best attacking option. Photo: FRANK REID
