Scroll down and click through to see who shone and who struggled for Graham Potter's men, who are still searching for their first home win of the season.
5. Tariq Lamptey - 7/10
Always looking to get forward and cause a problem, Lamptey was Brighton's brightest spark. Despite being small in stature, he won a header before forcing the own goal. Won an intriguing battle with Grady Diangana, who was substituted (Photo by Andrew Couldridge - Pool/Getty Images)
6. Ben White - 7/10
White looked assured and confident in the middle of the park, breaking up play well and a fantastic sliding challenge shortly before the hour mark stopped a goal scoring opportunity. However, he was turned relatively easily for the equaliser (Photo by Andrew Couldridge - Pool/Getty Images)
7. Yves Bissouma - 6/10
Comfortable but unspectacular in the middle of the park as Brighton dominated possession in the first half but was unable to take control in the second period

8. Solly March 6/10
Quiet display from March but he played in a couple of dangerous passes. Had first shot on target in the second half. He was replaced by Alexis Mac Allister on 70th minute
