Bopara has scored two half-centuries to help England earn a pair of victories in Abu Dhabi and open an unassailable 2-0 lead in the four-match rubber. The action switches to Dubai on Saturday and Bopara wants England to be on their guard. "In any series when you go 2-0 up the mood is pretty good," the Essex right-hander told Sky Sports News HD. "But we are keeping our feet on the ground, especially after what happened in the Test matches. "We know what Pakistan are capable of. They are a very unpredictable side, they can come out hard in the next couple of games so we've got to stay aware and keep doing what we've been doing. "We haven't had a good one-day record in the subcontinent, so it would be a big thing for us to win out here." Bopara was an unused member of England's squad that lost the preceding Tests against Pakistan by a 3-0 scoreline. But he is not yet thinking England can return the favour with a whitewash of their own in the 50-over format. "I wouldn't want to get too giddy," said Bopara. "We've done that in the past - not as a team - but as an individual you get giddy and things go horribly wrong. "We are not going to look too far ahead. We need to keep doing what we have done in the last two matches, just worry about our skills and dealing with that Pakistan bowling line-up and, when we get a chance to bowl, dealing with their batting line-up."
