The 32-year-old announced in February that he would be joining Magners League rivals Ulster after five years with the club.

But he played a starring role in the Blues’ Amlin Challenge Cup final 28-21 win over Toulon, having a hand in two of their three tries as they battled back from 13-6 down to lift the trophy.

And after the Welsh side tasted European success for the first time, Rush has had a change of heart and Blues coach Dai Young has confirmed the influential No.8 is in talks about staying with the club.

“He’s in discussions with Ulster and us,” Young said. “He did make a statement early doors but obviously it’s up to him - we can’t do anything about it.

“We would love for him to stay but it’s up to him to make that decision. He’s got to make that decision and hopefully he will stay with us. It’s out of our hands pretty much.”
