The Argentine was outstanding in his sideâ€™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 Rangersâ€™ second with a tidy volley. "Theyâ€™ve made a huge difference, particularly off the field.
"Theyâ€™ve lifted everyone, made us realise that we can do better and youâ€™ve seen the results today on the pitch. Theyâ€™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."
