Tony Pulis believes Manuel Pellegrini ’ s job as Manchester City manager will be under threat if he fails to land a trophy this season . The West Bromwich Albion head coach insisted City must continue to be successful over the next five years to earn the global fan base of rival clubs . 'The pressure is he has to win , given the amount of money Man City have invested in players over the past years , ’ said Pulis . ‘ I don ’ t think it ’ s just at the top , it ’ s at the bottom . We ’ ve seen it with Gus ( Poyet ) , there comes a tipping point . There is always a tipping point at the top and bottom . That ’ s the industry we ’ re in . Tony Pulis believes Manuel Pellegrini ’ s job as Man City manager will be under threat if he fails to land a trophy . 'They pay the money for results . It ’ s a results business . ' He added : 'All over the world there are supporters following the Premier League . A lot of fair weather supporters . Of the new generation , 99.9 per cent will pick a team that ’ s been successful . 'So Man City need to be successful over the next four or five years to get a generation of supporters , like Liverpool did , like Man United did . Those big clubs need that support , it ’ s money in the bank for them . ' Pulis takes his side to the Etihad believing Pellegrini ’ s team will be at their most threatening , however , following their Champions League defeat to Barcelona . He thinks City can win all their remaining nine matches to mount a Premier League title challenge and that the only difference in the Nou Camp was Lionel Messi . Pellegrini is under pressure at the Etihad after City were knocked out of the Champions League by Barcelona . Yaya Toure 's Man City side struggled to impress as they crashed out of Europe on Wednesday . ' I think City now will be at their most dangerous , ’ said Pulis . ‘ Coming out of the Champions League I think they ’ ll really focus on their last nine games . The attitude at that football club will be : “ Can we win nine ? '' It ’ s up to us to go and give them a good game . 'You look at their squad , they have enough to win nine games . If they do , who knows ? I ’ m sure they ’ re talking about it . They are that good a group . 'We talk about playing against Barcelona , they are one player short in that game : Messi . He was the difference . 'He 's a game changer at the very highest level of his profession and that 's the difference . I 'm absolutely convinced if you put him in City 's team they would be through now , not Barcelona. ’ Pulis believes City could be at their most dangerous on Saturday after their midweek disappointment .
