Victor Wanyama is fast emerging as one of the hottest properties in European football. The central midfielder put in a powerful display against Barcelona last night, helping the Scots to a dream 2-1 win over the Spanish club.
The Kenyan was linked with Manchester City and Arsenal over the summer, as well as Manchester United who have recently been credited with pursuing an interest in the player for January, or next summer.
Now the failure of all three to take the gamble over the summer will be haunting them, as they realise the effect of his Champions League performances on his price tag.
With all the uncertainty over Scottish football amid Rangers' self-inflicted financial scandal, you wonder if a big bid had come in for Wanyama, say around £8 million in early July, the player would have pushed for the move and Celtic would have been tempted to take the money for a player they paid just £900,000 for a year earlier.
This season he has really kicked on, with his showing last night a real reflection of his ability and proof he can cut it against the very best.
Just a fortnight ago, Celtic boss Neil Lennon came out and said the player was worth £25 million, in a show of bravado and attempt to put off suitors. Nobody really bought that.
Suddenly after last night, suitors may just up their valuations. While £25 million may be fanciful, it is no exaggeration to suggest Celtic could get around £15 million for the powerful midfielder.
Debate over a reasonable price will go on, and no doubt several Celtic fans will back their boss on his valuation. After last night, the world is certainly coming round to mass appreciation of Wanyama's immense talent.
He impressed in the first game at the Nou Camp too, and if Sir Alex Ferguson and Arsene Wenger thought they might be able to pick him up for a snip in January and were playing the waiting game to see how he developed, it has backfired.
Over the summer there was a lot of debate as to whether a move then would even be a good thing for the midfielder, who had after all played just one season at Parkhead, with it suggested he would benefit from staying in Scotland for another year and playing regularly rather than risk spending lots of time on the bench for a Premier League club.
Advocates of that have certainly been proved right, because for the player this season simply could not be going any better. The big question is to where it will all lead...
How much is Wanyama worth now? What does his future hold?
