Cooper praised Leeds after his Swansea side lost 1-0 to the Whites at the Liberty Stadium in the Championship on Sunday.
Pablo Hernandez scored a late goal to secure all three points for the West Yorkshire outfit.
Cooper believes that Leeds are a good team, but the Swansea boss is not sure if the current side can do well in the Premier League.
Meanwhile, former Cardiff City striker Jay Bothroyd has given his reaction to the defeat for Swansea.
Cooper told the Yorkshire Evening Post when asked if he expected Leeds to now seal promotion quickly and how Bielsa’s side might fare in the Premier League: “I haven’t really thought about it to be honest. They’re obviously a good team, they have a clear way of playing.
“You have to match them in what they do and be ready for it because they’re good at it.
“Whether it’s enough to get them out of this league and then compete in the Premier League, I’m not too sure, you are better asking the Leeds staff rather than me. All I know is when you play them now it’s a really tough game.”
Leeds United will improve
Bielsa has improved the current bunch of Leeds players a lot, and it is a testament to his coaching that the team are on the verge of clinching automatic promotion to the Premier League.
True, the current side might not take the English top flight by storm next season, but the Whites are very likely to make signings in the summer transfer window to prepare for the 2020-21 campaign.
With a few quality players and Bielsa’s obvious coaching ability, Leeds would become a better team next season and would be able to give any opposition a run for their money.
