Josip Juranovic has fired a cheeky dig at Rangers as he talked up Celtic's chances of landing a treble this season.

The former Parkhead full-back switched to the Bundesliga in January as he moved to Union Berlin.

Juranovic has since discussed his love for Celtic and his emotions as he departed Ange Postecoglou's squad.

The 27-year-old hopes his side can add to the League Cup that they won against Rangers on Sunday at Hampden and it was clear he was watching on from afar for the build-up.

Asked if Celtic could win the treble, he told Football Scotland: “I hope so, that means I can have more trophies in my back pocket!

“It's nine points in front of, how Sakala said... 'the other mob!’. At Celtic, the Scottish league is competitive, maybe not as much, but you are playing against defensive teams and you need to score.

“Sometimes it’s not that easy. Then you have the Old Firm derby and you need to perform well. You also need to win the championship to get to the Champions League.

 “I watched maybe 35 minutes because I had a game against Bayern here. In my heart I knew that we – we! – would win the cup. I am still talking with my friends at Celtic. I wished them all luck and told them I would be watching them and that I was really happy that they won the first trophy, but not the last one this year.

“I am texting all the time with Joe Hart, Matt O’Reilly, Jota. Who else? Daizen Maeda, Liel Abada… I have a lot of friends there and I will keep in touch with them through their life.”

On the rivalry with Rangers, Juranovic said: “The Old Firm was my first game for Celtic. I played on the left side and it was really special.

“I think that is maybe one of the best derbies in the world. Just to see it and play in such an atmosphere is something unbelievable and I am really happy that I played there. At Celtic they accepted me from day one.”

On his transfer to the Bundesliga, Juranovic added: “I am fighting here for the Champions League. I was playing there at Celtic and I want to stay there.

"That’s the main reason why I moved here because it is a top five league and we are third in the table now. We want to improve on that still. And I want to hear the music again soon. I like Celtic, I love the club and I had 18 beautiful months there. If the Champions League gave me a reason to go back to Celtic Park then I would really love that. Yeah, that's my main target. We will see what will happen.”
