Watch head coach's post-match verdict on SAFSee.
Gus Poyet says he has learned a lot from his first game in charge as the Black Cats suffered a 4-0 defeat at Swansea.
An even first half gave way to a second period in which the hosts notched a quartet of goals to leave Poyet to reflect on defeat in South Wales.
And the Uruguayan absorbed plenty ahead of his first full week working with the squad in its entirety following the international break.
"As a manager you learn a lot from watching your players on the pitch - you can see which ones turn it up a gear and which ones put their heads down [after conceding a goal]," he told SAFSee afterwards.
"The biggest thing for me today is that I have learned a lot from my players.
"It’s not an excuse, but five or six of the players in the team today have not been with me for the last two weeks. They were able to play their part today but not for the full game.
"At this level, if you’re losing a game 1-0 or 2-0, you are still in the game, it’s very important we stay in the game until the last minute and that’s something we need to make sure we do."
"It’s early, I don’t want to talk too much, but I do want to make sure that we learn from the game today.
"We didn’t do what we needed to do and we paid the price."
