Pietersen said his 22nd century that has brought him level with Walter Hammond, Colin Cowdrey, Geoff Boycott and skipper Alastair Cook, would be more cherished if the team wins on Monday.
He described the Wankhede wicket, on which 15 wickets fell during the third day, as a difficult one.
Pietersen was also all praise for his team's spinners -- Graeme Swann and Monty Panesar, saying the duo varied their pace.
