PEDRO CAIXINHA insists he hasn’t been distracted by the situation surrounding striker Kenny Miller ahead of Sunday’s Betfred Cup semi-final with Motherwell.

The 37-year-old has not played for Rangers since the Old Firm defeat to Celtic last month amid murmurs of dressing room discontent at Ibrox.

Miller’s agent, Dave Baldwin, hit out at his client’s treatment this week after he was dropped from Caixinha’s squad and sent to play with the Under-20s at Brentford.

Caixinha once again refused to be drawn on the issue and has attempted to draw a line under any talk about one of his most high-profile players.

He said: "It is [frustrating to still be discussing this] but I need to be polite in some moments and kind and respectful. In others I need to be abrupt and say it is time to place a period on this issue.

"Am I distracted? No. Nothing distracts me. I'm a guy who places my focus and follow my focus. Nothing can distract me.

"You know me. One of the good characteristics I recognise in myself is that I do not give up. I'm too persistent. When I want one thing, I just go for it.

"I'm very demanding. I'm never happy, I'm never satisfied. So I'm very focused on my work."
