Mehmet Ali said his team delivered an improved second-half performance in Friday's 1-0 win at home to Middlesbrough under-21s.
We took the lead early in the second half when Bradley Ibrahim played a great ball over the top to Ismael Kabia, who made no mistake when he rounded the goalkeeper and tucked the ball into the bottom left.
But Mehmet was frustrated with elements of our performance, particularly in the first half.
"In terms of the performance, I think we have frustrations as a group of staff and players," he said. "Credit to our opponent, there's a reason why Middlesbrough have only lost one game in PL2 so far this season.
