West Ham United v Manchester City: Pablo Zabaleta calls for calm as Manuel Pellegrini's men eye quadruple Having inflicted a 6-0 defeat on West Ham during the semi-final first leg at the Etihad Stadium a fortnight ago, Manuel Pellegrini's team must complete the formality of the return at Upton Park on Tuesday evening before securing their place at Wembley on March 2 for a final against either Manchester United or Sunderland, who play their second leg on Wednesday. With City just one point behind Premier League leaders Arsenal and facing an FA Cup fourth-round tie at home to Watford on Saturday, it appears that the Champions League last-16 encounter with Barcelona next month offers the most serious threat to the club's prospects of winning all four competitions this season. "We need to calm down," Zabaleta said. We know how tough it is to win four competitions. We are still alive in all of them, which is fantastic for the team at this point in the season and we will try to win all of them. But we don't need to get confused and think too much about it. We just need to go game by game and see what happens. Despite their seemingly insurmountable six-goal lead over West Ham, Zabaleta insists that City must approach the second leg as though the tie remains in the balance. "It doesn't matter about the first leg," Zabaleta said. We have to go into that game thinking it's a new game, even though we have six goals. We need to try and win it - like we are doing in other games at the moment. We are winning games and working hard. West Ham are in a tough moment, they are at home and will want to win it. So we need to take it seriously and we will. City manager Pellegrini is set to make wholesale changes to the team who defeated Cardiff City 4-2 at the Etihad Stadium at the weekend, with injury-ravaged Stevan Jovetic in line for a rare appearance.
