Celtic captain Scott Brown is hoping left-back Kieran Tierney stays with the club as they try to win their ninth Scottish league title in-a-row.
The 22-year-old Scotland international has been linked with a move Arsenal throughout the summer, in a deal expected to be worth around €27 million (£25 million).
Speaking in a press conference Brown said, "he's looking forward to trying to get himself back into training and get himself back on the pitch as well. He's been a phenomenal player for us for the last five seasons.
"We'll just wait and see what happens but here's hoping he stays. As it stands he's a Celtic player and I'd love him to stay because of what he's done the last five seasons. There's always going to be speculation on top-quality players and that's what Kieran is.
"There will always be speculation whether he goes through this window to the next window, it will always be there. That is what we expect when the team is doing so well and we're doing well in Europe, and he's performing well in Europe. It will always be there or thereabouts."
Last season the Glasgow club completed a historic third-straight treble, and are closing in on Rangers' record of 54 league titles. Scott Brown is confident Celtic can add their 51st championship, "we have managed to go the last eight seasons, which is fantastic for us, and we need to push this season the exact same. We will be pushed very, very hard again all the way through but we have the players and a manager who has belief in us as well that we can go and do it.
"There's always going to be a strong challenge. Rangers, Aberdeen, Hibs, Hearts, they always push us all the way. It's going to be hard this season as it is every other season but we are looking forward to that challenge. Our main aim just now is to start the league well and try to get the Champions League as well."
