Manchester City's hopes of beating great rival Manchester United to the Premier League title could hinge on suppressing a striker whose blistering run of goalscoring form has left Newcastle on the brink of Champions League qualification. Papiss Demba Cisse has been tearing defenses apart since his transfer in January, with two stunning strikes in Wednesday's 2-0 win at Chelsea taking his tally to 13 goals from 12 games. If City can keep Cisse quiet and follow up its crucial victory over United on Monday with a win at St. James' Park on Sunday, Roberto Mancini's side will likely go on to claim a first title since 1968. With two matches remaining, City is ahead of United on goal difference, while Newcastle is level on points with fourth-place Tottenham.
