Ajax seek repeat of shock win over Barca

Barcelona are calm heading into tonight's Champions League Group F game at Ajax despite consecutive defeats in La Liga, according to coach Luis Enrique.

Alarm bells are ringing at the Catalan club after they followed up a 3-1 defeat at Real Madrid in the 'Clasico' with a poor display in a 1-0 defeat at home to Celta Vigo at the weekend.

A win at Ajax could put Barca through to the last 16 of Europe's elite club competition if the other result goes their way and Luis Enrique said it was positive Barca's next game had come along so soon as they can use it to help get their season back on track.

"The team seem very calm to me, despite the last match when strange things happened," the former Spain midfielder said.

"What concerns me is that the team improves and until that becomes impossible I will remain optimistic," he added.

Barca are second in the group on six points, one behind Paris St Germain, who beat them 3-2 in the French capital at the end of September. Ajax are third on two points with APOEL bottom with one.

Barcelona will go through if they win and APOEL fail to beat PSG, while Ajax need at least a point to retain any real hope of qualifying and could be eliminated if they lose.

Tonight's game marks a return to Ajax for Uruguay striker Luis Suarez, with whom he made 110 appearances between 2007 and 2011, scoring 81 goals.

"I would love to get my first goal but out of respect for this city I would not celebrate it," he said.
