Furious Philippe Clement branded the decision to send off Rangers ace Jefte as the worst decision he's seen in his career.
The Ibrox boss was left fizzing after referee Marco Guida produced a second yellow after Jefte had won a header in the second half at Hampden.

Due to the decision being a second yellow card and not a straight red, VAR could not intervene in the incident with Jefte forced to trudge off the pitch in disbelief over the call in the Champions League third qualifying round.
And Clement appeared to confront Italian whistler Guida at full-time as he fumed over the huge decision - Jefte had been sent off with the scores at 0-0 before Dynamo Kyiv went on to win 2-0.

You expect a better level in decision-making, because this is for me the worst decision I've seen in more than 30 years.
“Especially at this level, when there is so much at stake. I have a lot of things in my head, but you guys [the media] know that every word I say is too much. I can get a ban also for the next European game, so let's keep things in my head.
