Sky Sports pundit Andy Walker says its time for Celtic to part company with manager Ronny Deila following their 2-1 defeat to Aberdeen at Pittodrie.It was a miserable night for the Scottish champions, who have now suffered back-to-back defeats following their shock loss against Ross County in the Scottish League Cup semi-final last weekend.Celtics lead at the top of the Scottish Premiership was cut to three points as goals from Jonny Hayes and Simon Church earned Aberdeen a 2-1 victory and former player Walker says owner Dermot Desmond has a big decision to make over Deila, who claimed on Tuesday he has the boards backing. He told Sky Sports: I didnt see any reaction from the Celtic players today after the weekends defeat to Ross County.I didnt see any reaction during the game against Ross County and I didnt see any reaction when they went 2-0 down tonight and I think you can ignore what the Celtic board are saying.This is now a call for Dermot Desmond. If he has got his finger on the pulse of the Celtic support, who continually booed the players at the end of the game, then he will realise hes got a big decision to make. Ronny Deila admits Celtics 2-1 defeat to Aberdeen puts pressure on him Do you trust Ronny Deila to come up with the type of results that will not only get Celtic the title but a bit of success in Europe?If it was up to me I would change the manager tomorrow.Deila has been under pressure all season following his teams early exit from the Champions League against Malmo.Desmond has previously backed his manager, claiming the team is better than they were last season, but Walker says performances are not good enough for a team that has a huge financial advantage over their domestic rivals. Aberdeen are now just three points behind Deilas side He added: Celtic have a huge advantage in terms of resources and everything you want.How did they defend tonight? The amount of long balls that were played when Celtic were 2-0 down and they didnt go and compete for them.I know thats not down to the manager but the manager has to make the kind of changes and type of signings that can get Celtic success on the park and all of that is up for serious debate. Celtic captain Scott Brown battles with Jonny Hayes on Wednesday night Its not good enough and Celtic could well go on and secure the title but would you trust this manager to get you the type of results the Celtic supporters are looking for?I think if you have got your finger on the pulse of the Celtic support I think there is a growing number who dont buy into what Ronny Deila is continually saying.Theres no improvement, theres nothing special and theres no notable victories and I think as a Celtic manager that is what you have to come up with.Also See:Match reportAs it happenedTableLive on SkyCheap Air Max 90 Uk . -- Patrick Reed got an early start in golf.

He stood up for the right to exercise Amendment 1.Speaking Wednesday at the Team USA Awards, the first U.S. Olympic Committee event theyve been invited to since their protest, Smith says hes backing Kaepernick because his protest is proactive and Carlos says theres no better platform than sports to stand up for something, even if it brings criticism.Protest is a good thing because youre trying to expose certain things through protest, said Carlos, who won the bronze in the 200. Then, when you sit back and say, `Well, I dont know whether its the right place to make statement here or there. In any protest, I think you make a statement to try and reach the far ends of the earth. What better way to do it than if youre in a sport.Several athletes have followed Kaepernick, who sat for the anthem, then modified his protest to kneel during it. Some have raised their fists like Smith and Carlos.Most recently, Nebraska football players Michael Rose-Ivey, Mohamed Baarry and DaiShon Neal kneeled during the anthem before a game at Northwestern, drawing criticism from Nebraskas governor.dddddddddddd. Rose-Ivey is expected to meet with the governor to discuss the issue next week.It is a sacrifice to deal with anything other than status quo, Smith said. As we know very well.While Smith said its important for athletes to study and understand why theyre protesting and what they want to come out of it, Carlos said backlash is part of the process.Any individual that makes a public statement or a public scene is saying we have issues that we need to deal with and we can no longer stick them under the rug or stick them behind the bus or what have you, Carlos said. By bringing attention to society, for them to be able to determine themselves why it was necessary that we take this thing called racism, violence and prejudice and bury it once and for all.It has taken almost half a century for the USOC to welcome Smith and Carlos back into the fold after being on the outside for breaking the rules. Carlos called their return a rebirth and both men hope they can be ambassadors and a positive influence on young people who werent born when they protested at the Olympics.We never denounced what we stood for, Carlos said. We stood for humanity. At the same time they loved the fact that we had courage. Thats what you need in athletics. For them to come and lower the drawbridge so to speak and welcome us across with open arms, its a beautiful situation. I dont think it gets any better. ' ' '
