Wenger wants Gunners to be 'ruthless' against Barca

Arsenal manager prods squad ahead of Tuesday clash

Manager Arsene Wenger wants his Arsenal side must be more "ruthless" against Barcelona than the Gunners were against Hull when the Champions League holder takes the pitch at Emirates Stadium on Tuesday.

Wenger's team was left frustrated in a scoreless draw against second-tier side Hull City in Saturday's fifth round of the FA Cup ahead of the first leg of their Champions League last 16 tie against the Catalans.
