Sunderland boss Jack Ross has led his side to three victories in three matches.
Sunderland are currently building up to taking on Plymouth Argyle at the weekend.
And Ross said that Sunderland’s training session was of such a high quality that it reminded him how much talent was in his squad.
“The group of players trained brilliantly this morning, it’s one of the sessions as a manager where you think we’ve got a really good squad here,” Ross said.
“They were really at it and I think that reflects how they feel at the moment.”
Sunderland have won their last three matches on the bounce, as they continue to push up the League One table.
The Black Cats have put pressure on the top two now, as they aim to break into the automatic promotion spaces.
Sunderland are currently just one point behind second placed Peterborough United, with a game in hand.
Ross’s side head into their match against Plymouth on the back of a 3-0 victory over Southend.
Plymouth are also in strong form, after winning their last two League One matches in a row.
