The Argentine was outstanding in his side’s 3-0 win at Wolves on Saturday, scoring the second and barely misplacing a pass.
"The club feels different since they arrived," said the 25-year-old, who scored Rangers’ second with a tidy volley. "They’ve made a huge difference, particularly off the field.
"They’ve lifted everyone, made us realise that we can do better and you’ve seen the results today on the pitch. They’re nice people and they come with the experience of having played at this level for a long time. The group is working well together now."
