Jol said: “They have to grow up and be more physical and stronger. We did not win enough 50-50s.
“I can’t recall Arsenal playing at home and only creating one or two chances, instead of six, seven, eight. So that should have helped.
“The decisions didn’t help but I can’t complain about them because that would be stupid after the way we played.
“We played them twice last year, dominated both games and drew both when we should have won. That is why I feel we’ve taken a step back. We’re not as strong, even though we’ve got more talent.”
