I wouldn't really say the results are worse though Turkish, and if they are it is only slightly...
It seems to me that as far as you're concerned 'performance' includes the result, which OLallana is classing as two different things (I tend to agree that performance and results are different. For instance, I would say our performance in losing 3-2 to Man City was worse than our performance in losing 2-1 to Man Utd, yet both yielded a 1 goal loss).
