West Ham United striker Andy Carroll could do his former club Liverpool a massive favour against Manchester City, who are the team he has scored most against. Carroll, who has scored just twice this season, will come up against the side that he has found most joy against in his career on Sunday as West Ham travel to Manchester City. In 13 appearances against the Citizens, Carroll has scored five goals, including netting the last time he played against Man City in a 2-1 defeat for West Ham in April 2013 at the Etihad Stadium. Carroll scored twice both for Newcastle United and Liverpool against Man City prior to joining West Ham on loan last season, where he has since made a permanent move. Liverpool, who face Newcastle at Anfield, need West Ham to pull off a major upset and beat Man City on the final day of the season if they are to claim a first league title in 24 years.
