AC Milan midfielder Riccardo Montolivo says they must keep it tight against Champions League opponents Barcelona.
Montolivo insists Milan will have to stay compact if they are to have any chance of beating Barcelona on Tuesday.
"We need a high level of concentration and attention, limiting the spaces between the lines," the midfielder told Milan Channel ahead of the Champions League tie.
"We need to be compact and use the counter-attack. The squad spirit, the attitude and the approach are fundamental to doing well against Barcelona."
