Paul Merson believes Premier League leaders Manchester City have "no way" of winning the title despite their 5-3 win over Sunderland making it five wins from five under Enzo Maresca. City lead Arsenal by three points after the Gunners' 3-0 loss to Brighton, but Merson insists City's defensive chaos will catch up with them against top teams. "You can't keep scoring loads of goals to win football matches," he said. "Sunderland are not the most high-scoring football team in the country but they scored three goals - and could have scored more." Merson noted Maresca dislikes chaos and referenced City's 10-man win at Old Trafford, arguing United were the better team 11 versus 11. On Arsenal, Merson questioned Mikel Arteta's decision to play Bruno Guimaraes over Myles Lewis-Skelly at Brighton, saying Arsenal were "outrun" and "overpowered in midfield." He suggested Guimaraes suits low-block games but not high-tempo matches, adding Arteta may regret the selection.
