The Bhoys could fancy their chances of making a stunning signing next summer if the former Liverpool defender's move is a success.

Celtic's signing of Kolo Toure this week from Liverpool has been met with plenty of positivity from Bhoys fans.
The 35-year-old had a mixed three years at Anfield, having signed for the Reds when they were managed by current Celtic manager Brendan Rodgers. However, towards the end of last season as he saw game time for Liverpool, the former Arsenal and Manchester City captain proved once again that he is still a quality defender.
Though he has only signed a one-year deal in Glasgow, there is a good chance Toure will get plenty of football for the Bhoys as they look to compete on as many fronts as possible this season. If he does well over the next 12 months, there is every chance his stay will be extended.
And if that is the case, Celtic could have the possibility of making a stunning addition next summer.
Because that is when Manchester City star Yaya Toure's, Kolo's younger brother, contract at the Etihad expires.

It may be hugely speculative at this early stage of the centre back's career in Glasgow, but of course there is some form when it comes to one international footballing brother joining another in Scotland.
Celtic's bitter rivals Rangers had both De Boer twins, Ronald and Frank, at Ibrox for a period in 2004. Ronald de Boer had arrived four years earlier and had obviously convinced his twin of what it is like to play for one of the Old Firm.
There is no reason at all that Celtic couldn't do the same with the Toure brothers, and the fact Liverpool were linked with Yaya when Rodgers was in charge, according to a Liverpool Echo report back in 2014, shows the Irishman appreciates the player.

The two Ivory Coast legends started their careers together at ASEC back in their homeland, but the only other time they played for the same team was at Manchester City, where they won the FA Cup in 2011 and the Premier League a year later.
Could they end up in Glasgow together?
If Celtic pulled it off, it would be a magnificent signing, and would hark back to the glory days of world class players in the top flight in the 90s, when the likes of Henrik Larsson and Bryan Laudrup starred in Scotland.
And it would also make for some great chants around Celtic Park.
