BARNSLEY ended their pre-season campaign with their first loss on Saturday against the Premier League champions.
The Reds faced Manchester City on Saturday evening, losing the fixture 4-0.
Pep’s team were 3-0 up at half time, and it could have been worse for Barnsley had City not missed a penalty before the break.
It was a meeting of two former team mates as Markus Schopp played with Pep at Italian club Brescia in the early 2000s.
City’s first goal came for Samuel Edozie, who tapped into an empty net following a Mahrez cross.
The second goal was similar after Mahrez’s low cross was tapped in by Ben Knight.
The Algerian got the third as he volleyed in to make it 3-0 before half time.
Reds keeper Brad Collins stopped the score from getting worse as he saved a Cole Palmer penalty, after he was fouled himself by Cauley Woodrow.
It was 4-0 midway through the second half after Nathan Ake slotted home.
This was Barnsley’s only pre-season defeat and the Reds will play Cardiff in the Welsh capital this weekend.
