The 21-year-old spent last season on loan with Mark Warburton's Glasgow Rangers side.
The former Tottenham youngster spent last season on loan at Ibrox and was part of the Gers side that clinched promotion back to the Scottish Premiership, won the Challenge Cup and knocked Celtic out in the semi-final of the Scottish Cup.
Ball left Tottenham on a permanent deal this summer
However, the 21-year-old has hinted that it would be wrong to suggest that he has already played his last game for the Light Blues.
"I absolutely loved my time at Rangers and I would love to go back at some point. We will see how my career pans out and what lies ahead for me," he told the Evening Times.

"It is a great place to go and play and for me last year it was perfect. It was at a good level, a good challenge and at a huge club. It is good for any player to go there.
"I loved being at Ibrox and if I can get up to watch the team play then I would love to do that. If there is an opportunity during the season I will go back up and see the boys and the fans again."
While the season is still very much in its infancy, the early signs suggest that a fairly swift return may soon be an appealing option for the defender.
Mark Warburton's men have made a promising start to life back in the top flight, winning two and drawing one of their opening three games, while the Millers have won just once in the first four fixtures and find themselves in the bottom three in the table.
And if both sides ultimately finish their respective seasons in a similar position to where they are now, Ball would surely find it impossible to turn down an Ibrox return if Rotherham were relegated and Rangers booked their place in Europe ahead of next term.
