Celtic manager Ange Postecoglou has claimed it is not guaranteed that Aaron Ramsey will succeed with Old Firm rivals Rangers.
The Wales international joined the Scottish champions on deadline day on loan from Juventus until the end of the season, having endured a tough time in Italy. While he won a Serie A title and the Coppa Italia with Juve, he struggled for fitness and opportunities, with Massimiliano Allegri affording him few chances this season.
He joins a Gers team currently two points clear of Celtic in the Scottish Premiership title race, with a derby set to take place on Wednesday.
Speaking ahead of that game, Postecoglou said he remains focused on his own players and pointed to Kyogo Furuhashi as an example of a player who has gone to Scotland and made an impact.
He said: “I don’t really get affected by what others do. I’ve said it before: my focus is on what happens here. You can’t start worrying about what other clubs could potentially do or what players they bring in.
“Ultimately all these things come down to performances. No one had heard of Kyogo but you can’t tell me he’s not had an impact. It’s more about the impact they have. When opposition sides bring in new players it’s about looking how they perform and how they fit in and us trying to counteract that.
"Are there no guarantees? Absolutely. And it’s not an easy league to do it in. It’s been proven before. But my perspective is on us.”
Rangers manager Giovanni van Bronckhorst said: “To be able to bring in a player like Aaron was a very good opportunity for us. He will bring experience and quality to the squad. It is too soon for him to be involved [against Celtic] but I expect him to be in the squad really quickly.”
Rangers also brought in James Sands, Amad Diallo and Mateusz Zukowski during the January transfer window.
