Barcelona coach Luis Enrique paid tribute to assistant Juan Carlos Unzue after their Champions League win at Borussia Monchengladbach.
Unzue is in charge of Barca's set-pieces and Enrique praised his assistant's influence.
"The strategy helps us win games and it is clear that the planning of Unzue has worked swimmingly," smiled Enrique.
"I sincerely believe that the victory was just.
"It was not easy to win here because I want you to remember they had 18 straight games without losing, with eleven straight wins, so you can see how difficult it is to win here."
