Pakistan v England: Alastair Cook calls for 'mental toughness'

England opener Alastair Cook says the team's top six batsmen will need to show "serious character" if they are to have any chance of rescuing the third Test against Pakistan in Dubai.

Pakistan took control of the match on day three as Younus Khan (115 not out) shares an unbroken third-wicket stand of 194 with Azhar Ali (75 not out)

Cook admits a cluster of wickets in the first session on Sunday is essential if England are to try and avoid a 3-0 series whitewash.
