Southampton midfielder Victor Wanyama believes Champions League football is a possibility for the club.
The 22-year-old, who played in the tournament for Celtic, left the Hoops for St Mary's in the summer for £12.5m after being linked with Liverpool, Arsenal, Everton and Cardiff.
"I believe one day Champions League football is achievable at Southampton," the Kenya international said.
"Everything step by step and I believe one day we will be also there."
He scored for Celtic in their famous 2-1 win over Barcelona at Parkhead last season but said the time was right to move when he signed a four-year contract with the Saints.
"Obviously Champions League are good games, but it was time for me also to move on," he said.
"It was my decision after meeting with the chairman and the manager - the ambition of the club they had. I was just happy to come and join them."
Southampton have won one, lost one and drawn one of their opening three Premier League matches and face West Ham, who have exactly the same record, on Sunday.
"I think it is going to be a hard game, but we are ready for it and looking forward to the challenge," Wanyama said.
"We have been working hard and we had some good results, and also some bad ones, but I think we are still on track and looking forward to doing well."
