Chilwell said Amorim have been given enough time to refurbish United but he has failed. How many seasons have Amorim used in the club that he's calling enough time. At least, from the look of tgeor performance this season, there's improvement. Is just that they are lacking the final touch to make all their efforts yield to a goal. I believe with time, the goals will start pumping in.
He does not have to stay several seasons for his performance to be assessed and judged if necessary,, waiting several seasons long before judging will only be detrimental to the team, it is only decent for Amorim at this time to accept that he is close to failing and try making moves towards doing even much better so that he will not end up in causing the team another season without a trophy or even a good performance to fall back at. This is why it is mostly best that the coach be made to understand there is a continuous assessment on him even as he has not been there for the longest of times so he will be able to keep that at heart while hee works.
