The Eagles were second best in a first-half of little fluidity, in truth, from either side, going in two goals down at the interval – but rallying to make it a close contest in the second period thanks to goals from Yéremy Pino and Daichi Kamada.
“I think it was a difficult first half,” Mitchell admitted, speaking to TNT Sports.
“I think the second half was much better, so I'm kind of disappointed that we didn't start off like we did in the second half – but we have to keep working.
“I wouldn't say anything was missing, we had all the information, but I don't think we, as players, executed it well in the first half. I think we did much better in the second half.
“I don't think it was confidence, I think it's one of those days. Sometimes it goes well for you, sometimes it doesn’t. I think in the first-half we gave ourselves a mountain to climb, but in the second-half it was much better.”
On what inspired that change, Mitchell said of Manager Pierre Sage: “He just told us how good we can be and how we're not performing at the moment, and we need to perform.
"It kind of pushed that confidence back in us that we're good enough, we can do it, and obviously in the second-half it was much better.
“Of course we want to keep a clean sheet all the time. Sometimes it doesn't happen, sometimes it does. But as a back five, as a defensive unit, we're just trying to get better each game."
