RANGERS’ loan flop Carlos Pena is under fire in Mexico after brazenly buying six cans of beer immediately after training in his club gear.

The midfielder is back in his homeland with Cruz Azul after ex-Ibrox boss Pedro Caixinha recruited him on loan.

He’s hardly played since he returned though and was slammed last week by Caixinha, who warned him that he would be sent back to Glasgow at the end of his loan spell if he didn’t shape up.

But he’s not helped himself after he was spotted in an off licence next to his club’s La Noria training complex immediately after morning training.

Pena purchased six cans of beer before driving off, which caused uproar among Cruz Azul fans after this was widely reported in Mexico City.

The 28-year-old, who has earned 19 caps for Mexico, joined Rangers from Liga MX side Guadalajara in his homeland last summer for a transfer fee of around £2.5m.

However, the attacker made just 14 appearance for Rangers, scoring five goals in the process but struggling to justify his fee and was sent on loan in January.

Meanwhile, Caixinha’s own problems deepened after he was handed a two-game ban from the dug-out by the Mexican League after he was sent off at the weekend.

The Portuguese boss was ordered off in his side’s 2-2 draw at Tigres in a Liga MX encounter and he’ll be forced to sit in the stand for his club’s next two games.
