Christian Abbiati believes that AC Milan's performances have got worse in recent weeks after the Rossoneri lost 4-1 to Atletico Marid on Tuesday.
The Italian giants enjoyed a revival of sorts following the appointment of Clarence Seedorf as Massimiliano Allegri's successor in January after going through a poor start to the season.
However, they have now lost four of their last five games in all competitions, including their 5-1 aggregate Champions League exit sealed at the Vicente Calderon.
"It was a particular game and we've taken steps back with respect to recent performances," he told the club's official website.
"We didn't play well in Udine and tonight we definitely took another step back. We knew it wouldn't be easy and after Ricardo [Kaka] got the equaliser, we crushed them.
"It was a shame about their second goal as the deviation put it right in the corner. It's disappointing to go out of the Champions League like this and we have to recharge our batteries as on Sunday we'll be up against a team that's playing well.
"Now it's very important to focus on the league as we have 11 games ahead of us. From here to the end of the season, all us players will be under examination. All of us have to show that we're able to wear this jersey."
The San Siro outfit have a chance to bouce back at 15:00CET on Sunday, when they host Parma.
