Egypt boss Javier Aguirre is concerned about the decline in performances of his side in second-halves of their two Africa Cup of Nations games to date.
The Pharaohs boss was speaking after their 2-0 win over DR Congo on Wednesday, a victory which was secured courtesy of first-half goals from captain Ahmed Elmohamady and Mohamed Salah, which took them into the Round of 16.
For a second successive game, however, the host nation seemed to fall off after the break, which Aguirre revealed is a cause for concern.
