Against Ajax, Barcelona could have Carles Puyol back. The 35-year-old defender returned to training on Friday after recovering from knee surgery.
With defender Jordi Alba sidelined due to a hamstring injury sustained in the Sevilla match, Puyol could reinforce a back four that has looked fragile at times and provide help for Gerard Pique and Javier Mascherano.
"The team is getting its captain back and we have the center back we wanted," Martino said.
Ajax arrives ater a 2-1 Dutch league win over Zwolle, where coach Frank de Boer brought on forward Bojan Krkic in the second half.
The 23-year-old Krkic, who came up through Barcelona's training school and scored 26 goals in 104 appearances for the first team from 2007-11, said playing against such a great team "should motivate us."
