Leeds United fell to their 15th loss of the campaign with a 2-0 defeat against Brighton and Hove Albion at the AMEX Stadium on Saturday afternoon.

The Whites, who weren't at their best, remain in ninth place in the Premier League table.

  • Why did your side's performance levels drop off so much today compared to the last games?

Goals from Pascal Gross and Danny Welbeck sealed the three points for Graham Potter's side against Marcelo Bielsa's men, a result which saw Brighton collect six points from Leeds this term.

After the game, Bielsa spoke to the media to explain why his side's performance levels drop off so much compared to the last few games.

"Fundamentally, it was due to a certain sector on the pitch where we couldn't prevent their three centre-backs from playing the ball out cleanly, nor could we overcome them." he explained.

  • Can you explain why there were no Kalvin Phillips or Helder Costa?

Leeds were without Kalvin Phillips and Helder Costa for the clash with the Seagulls on Saturday afternoon.

And at times it looked as though the Whites missed England international Phillips in front of the back four and Bielsa confirmed why both players were unavailable at the AMEX.

"Kalvin [Phillips] received a knock which created a hematoma behind his knee," he revealed.

"And Helder [Costa] received a very big knock in his back and this impeded him from playing the game today," he added. 

"The knock he received was in the game against Manchester United where he was substituted."

  • What did you make of Robin Koch as a defensive midfielder today in what was a difficult day for the whole team?

Defender Robin Koch played in front of the back four in the absence of Phillips this afternoon and the German international didn't produce a good display in that role.

Having said that about Koch, the whole team were not at their best against Brighton and Bielsa discussed Koch's performance.

"I think he played well," Bielsa said. 

"It was very difficult for anyone to shine according to how the collective play went.

But I tell you, it's very difficult to play well, but he didn't play badly in a collective performance that was in the medium, it was not easy," he added.

  • Was there anything Patrick Bamford could have done differently to affect that he had no real service today?

Leeds United striker Patrick Bamford didn't really have anything to work from this afternoon and at times he was coming back into his own half to get a touch of the ball.

Bielsa was asked if he felt that Bamford could have done anything different to affect the situtation.

"No I think not," he confirmed.

"We had a problem in the creation prior to the ball reaching Patrick [Bamford], where he had no influence and he could not receive the ball in positions where he can cause harm to the opponent.

When we can't overlap out-wide and when we can't give the pass from the centre from a closer distance, it is difficult for him to shine," he admitted.

  • What was the thought process behind substituting Ezgjan Alioski at half-time - tactical or was it to try and change things up?

Leeds defender Ezgjan Alioski was substituted at half-time for Ian Poveda during the Whites' defeat against the Seagulls and it wasn't one of his best performances in a Leeds shirt.

Alioski was at fault as he clumsily upended Welbeck for the penalty which gave Brighton the lead and after the game, Bielsa explained the reasoning behind the substitution.

"I wanted to position natural winger on the right-hand side because in the first half we were able to get to that sector easily, and I thought that Dallas playing from a deeper position could create a little bit more," he revealed.
