Manchester City gave their Champions League credentials a huge boost on Saturday afternoon with a 5-0 demolition over struggling Crystal Palace.The Citizens have the capability to pull off results like this more often than they do, especially with a manager like Pep Guardiola in the hot seat, but whether he's as effective in the Premier League as he is in Germany and Spain is still up for debate.But one thing that can't be denied is how good their squad is. With the talent at their disposal they should definitely have made more of a challenge for the title than they did.David Silva, Vincent Kompany, Kevin De Bruyne, Raheem Sterling and Nicolas Otamendi all got themselves on the scoresheet, though there were a lot of fans who missed out on the goalfest.In recent weeks, City's rivals have been trolling the club over their ongoing struggle to sell out their home ground, which is now often referred to as the 'Emptyhad'.Over the course of the season, City have struggled to sell out the Etihad for big clashes in the Champions League, let alone domestically, so a visit from Palace was never going to compare.And while the majority won't care what others say so long as they keep winning by such score lines, their hopes of being taken seriously as a big club will suffer if their fans continue to stay away.During the Palace match, Sky Sports cameras panned around the stands several times, showing just how many empty seats there were on the day.Fans watching at home noticed and took to Twitter to have a good old laugh at City's expense. And not only that, several commented on the lack of atmosphere being generated from the sidelines despite there being a glut of goals to celebrate.Check the reactions below...
