The third round of the world's oldest football cup competition kicks off with a cracker of a tie. West Ham United host Manchester City at the City of London stadium. Pep Guardiola came to Manchester City weighed down by mammoth expectations and although initially it looked like he would be able to work the same magic with City has he had previously with Barcelona and Bayern Munich, recent form suggests that the Premier League will be the Spaniard's biggest challenge yet. City are currently 4th in the league, seven points off leaders Chelsea and will need a good performance today against West Ham in order to relieve some of the pressure. The Hammers meanwhile also need a big result after losing their last two league games. They pulled off a big upset in the EPL Cup earlier this season by knocking out Chelsea. Can they repeat the trick here? (Kick Off 7.55pm)
