Jack Butland described himself as his 'own biggest critic' after his Crystal Palace debut against Wolverhampton Wanderers, but said overall he was pleased with his performance.
Reflecting on the game as a whole, he told Palace TV: "I think second-half we improved. I think for what we did do, it didn’t feel like we created much, which was a shame, but we were up against a good side and I just don’t think we found that spark.
"[We are] frustrated and, for me on a debut I’ve been looking forward to for a long time and hoping for a positive result, it’s bittersweet; nice to make my debut but also very frustrating to be out of the cup.
