Barcelona manager Gerardo Martino has said that his team will face a tough test in their Champions League match against Ajax.

The Spanish champions lead Group H with 10 points and will secure top spot with a win at the Amsterdam ArenA on Tuesday evening.

"I always considered Ajax as a great team who know what they need to do on the pitch," UEFA.com quotes him as saying.

"They are technically skilled and they know how to play. I know that we are going to face a difficult opponent and I am convinced that they can come second in the group.

"When I walk through the halls, I see the photos of the people who are responsible for the style of Barcelona. Many Dutch players, and also Ajax, have certainly been very important for the style of Barcelona."

Martino is unbeaten as manager of Barcelona since joining the club this summer.
