''It's very important we debrief this tour very thoroughly, like we do on any tour, and learn some lessons and don't walk away … But at the same time it's not all doom and gloom, you don't become a bad side overnight,'' Strauss said.England, who rose to No.1 in the Test rankings in August last year, continued to struggle in Asian conditions, with Pakistani spinners Saeed Ajmal and Abdul Rehman destroying them in the series. Off-spinner Ajmal took 24 wickets while Rehman finished with 19.
For England, Jonathan Trott was top scorer in the series with 161. Alastair Cook scored 159 and wicketkeeper Matt Prior finished with 150. Key batsmen Kevin Pietersen (67), Ian Bell (51) and Eoin Morgan (82) were major letdowns.
