After a record-breaking start to the season Barcelona have suffered a dip in form and face a stern test of their Champions League credentials against AC Milan on Tuesday night as they look to overturn a 2-0 first leg defeat to progress to the quarter-finals.
Barca only dropped two points from their first 19 games in La Liga to open up a sizeable lead at the top of the table but in the last two months chinks have started to show in their armoury, particularly in defence where they hadn’t kept a clean sheet in 13 games in all competitions until Saturday’s 2-0 victory over Deportivo la Coruna.
It is a far cry from Milan's own form as they notched a 10th league match in a row without defeat as they won 2-0 at Genoa on Friday night.
Much of Barca's problem has been caused by a failure to pressure with the same intent up the pitch, starting with the forwards, which has allowed the opposition to have more time on the ball and expose their defensive flaws, as was shown clearly in the first leg at the San Siro.
They also looked ragged and without ideas in the King’s Cup defeat by Real Madrid and while it could be argued that it is logical for a team to drop their form at some point during the course of the season, it has coincided with the absence of coach Tito Vilanova, who has been receiving cancer treatment in New York.
Except for one game against Espanyol in early January, it has been assistant coach Jordi Roura who has been leading the team.
Although he is in close contact with Vilanova, it appears as though he lacks the same discipline and strength of character to motivate the players.
However, he seems sure about how his team need to tackle Milan.
"It is an important game and the one that we have been focusing on. We are clear about how we are going to approach it," he said after the Deportivo game.
"We know how Milan are going to play and how we will do ourselves. I don't think there is a problem psychologically and we are all very much up for Tuesday’s game."
