Enrique seeks more precise Barcelona

Barcelona coach Luis Enrique insisted his side will need an improved display when faced with the very different challenge of former Barca boss Pep Guardiola's Manchester City after laboring to a 1-0 win over Granada on Saturday.

Barca travels to Manchester on Tuesday having thrashed Guardiola's men 4-0 less than two weeks ago to take a commanding lead of UEFA Champions League Group C thanks to a Lionel Messi hat-trick.

However, Messi, Luis Suarez and Neymar endured a rare off night in front of goal as midfielder Rafinha bagged the only goal against an ultra defensive-minded Granada.
