That's gonna be a blunder if palace will let him manage the club even longer. Palace may go down again to the relegation zone. everton has been showing good performance after it changed its coach. Palace may also try to follow the decision that was already made by everton to sack the useless coach to be replaced him with a new coach that has better competency to manage the club to be even better. Palace hoped that if the new coach will able to change the trend of club performance into this steadily going up. Palace will not try to make another mistake again by keeping using vieira as a coach. Vieira was not coaching the club for free. He has got big payment for that but he failed to bring the good results that will make the management of club satisfied with his performance.
Palace shall try to avoid the relegation zone. it will be so bad to see palace to be relegated from EPL.
