Arsenal manager Mikel Arteta urged his team to be wary despite sealing a 3-2 win over Chelsea in the first-leg of their English Football League Cup semi-final on Wednesday.

Arsenal took advantage of the multiple blunders committed by Blues custodian  Robert Sanchez, but Garnacho’s brace (57th & 83rd min) for Liam Rosenior’s side and a couple of costly misses in front of goal left Arteta mildly disappointed with the outcome.
