Liverpool boss Andoni Iraola says his side "needed" a clean sheet in their 2-0 friendly win over Como but warned they "need training" time in the weeks to come. Liverpool drew 0-0 with the Italian side in a behind-closed-doors friendly on Sunday and then won an encounter in front of fans at Anfield later in the day. "I think we need a little bit this feeling of finishing with a clean sheet, winning the game," Iraola said after the 2-0 success.
