Barcelona coach Tata Martino is excited to be making his Champions League debut tonight.

Barca will host Ajax to kickoff their campaign.

"For any manager, being in the Champions League means a lot for their careers," he said.

"We have high hopes for the competition."

Martino knows there's been doubts about his new system.

"We are used to criticism, especially because this is a team that has achieved such levels of excellence in recent years."
