Wigan Athletic boss Steve Bruce admits Amr Zaki wasn't match-ready for their defeat to Middlesbrough.
He said: "Zaki has set unbelievably high standards but he hasn't trained because he got a kick on the calf last week. That took the edge off him.
"I was worried after the first 30 minutes when we seemed to have really good opportunities. But you need to score when you're in the ascendancy in the Premier League.
"It was one those days when it didn't go our way but we didn't deserve to lose. It's an injustice."
