It's hard enough to play at this level, he can play at a world-class level in four or five different positions."Hagreaves went on to compare Foden to Manchester City legend David Silva. He believes the best is yet to come from the 21-year-old Englishman.He added:"The thing is with Phil he's one of one, he's the most unique footballer around, When you see videos of him playing when he's 10 he's half the size of everyone else but now I think Phil's still at the beginning of his development, I think there's much more to come. For me personally, I think he's David Silva, [his best position is] central. He's best on the half turn."Football on BT Sport@btsportfootball"If he continues at the rate he is developing, he goes down as arguably the greatest English player ever.""We all want to win, but he needs to win, he's obsessed!"Talent Mentality @JoleonLescott has seen firsthand how much Phil Foden wants it.#UCL10:37 PM · Apr 5, 202233231"If he continues at the rate he is developing, he goes down as arguably the greatest English player ever.""We all want to win, but he needs to win, he's obsessed!"Talent ✅Mentality ✅@JoleonLescott has seen firsthand how much Phil Foden wants it.#UCL https://t.co/YSZKVyKjQ4Phil Foden's impact off the bench vital for Manchester City in the Premier LeagueFoden is quickly emerging as one of Europe's top starsManchester United legend Rio Ferdinand was also hugely complimentary of the English midfielder's talents following City's victory over Atletico.He explained the way in which Foden can have an impact on Pep Guardiola's side off the bench, comparing his influence to former Premier League super-subs:"The composure that he's got, the ability he's got to draw players to him. His footwork, he causes havoc, he's got that clarity when he's running."Ferdinand continued,"I think also what's a good indicator is he comes off the bench and he's straight into it, that's an intelligence, that's concentration, that's an understanding. You talk about Chicharito [Javier Hernandez], Ole Gunnar Solskjaer and people coming off the bench, it's not an accident that happens."SPORF@Sporf🤩Pep Guardiola knew that @PhilFoden would be the key to unlock @Atleti!2:44 PM · Apr 6, 2022162🤩Pep Guardiola knew that @PhilFoden would be the key to unlock @Atleti! https://t.co/qW72siXHiKManchester City fans will be hoping Foden continues his fine form when they host Liverpool at the Etihad Stadium on Sunday.The clash between the two rivals has huge implications in the race for the Premier League title.
