Liam Rosenior admitted Chelsea paid the price for costly mistakes after Arsenal took advantage of his side's blunders to win 3-2 in the League Cup semi-final first leg on Wednesday.

Rosenior's team face a tough task to set up a final against either Manchester City or Newcastle following their error-strewn display in their new manager's first home match.
