Andrew Strauss believes that it is important for England to keep focused if they are to build on the first Test win over the West Indies.

The second Test begins on Friday at Trent Bridge, where Strauss expects the Windies to put up another tough test following the five-wicket win at Lord's.

Strauss told Sky Sports News: "It's hard work to get on top of the competition. It's hard work to finally nail that final nail into the coffin. The West Indies put up a really good fight.

"There were times there where they made life really difficult for us and I suppose we're relieved to a certain extent that we were able to get over the line and win that game.

"We're going to have to do it again this week if we want to win. It's all about keeping our feet on the ground and making sure we're willing to do the hard graft necessary to get on top of the side ahead."

Strauss's century in the first Test was his first ton for England in 18 months.
