Barcelona v Real Madrid: Lionel Messi seeks Barca improvement

Barcelona star Lionel Messi says his team need to "pull themselves together" if they are to overcome Real Madrid in Tuesday's Copa Del Rey semi-final.

Barca snatched a crucial away goal to draw the first leg 1-1 in the Bernabeu.

But the Catalans lost 2-0 to AC Milan in the Champions League last week and have failed to keep a clean sheet in their last 11 matches.

Messi, whose winner against Sevilla was his 38th league goal of the season, wants Barca to put those under-par displays out of their minds against their greatest rivals.

"We need to get back to playing how we were doing before and not think about what happened in Milan or the Sevilla game," he said.

"We have to pull ourselves together because there are some decisive games coming up.
