Carlos Pena made his full Rangers debut in their 3-1 Scottish League Cup win against Partick Thistle – and fans took to Twitter to rave about his display.

Pena opened the scoring with a second-half header in his first start for the Glasgow giants since his move this summer.

But Rangers needed extra time, and further goals from Daniel Candeias and Eduardo Herrera, to book a place in the Scottish League Cup semi-finals.

One of the main talking points among supporters after the triumph at Firhill was the performance of Mexico international Pena, who has been on the fringes of the team in the opening two months of the campaign.

They were hugely impressed by the 27-year-old on Tuesday night during his 71 minutes on the pitch and insisted the signs were positive ahead of sterner tests ahead.

Here is a selection of their messages on Twitter:

Central midfielder Pena has made five appearances for the Glasgow giants since his £2.5million summer move from Leon.

He has now scored twice, against Dundee as well as Partick, but his playing time for the club has amounted to 175 minutes and supporters will be keen to see more of their big-money new arrival.

Pena will hope to keep his place in the starting XI for Saturday’s Old Firm showdown against Celtic.
