When it comes to buying players, it's probably best not to base too much judgement on one or two performances.
At least, that's certainly the case with Moussa Sissoko.
The Newcastle Chronicle are reporting that the striker, who is being widely praised for his performance in the final of Euro 2016 despite France losing out to Portugal, is being valued at £35million.

It's a price tag that will no doubt bewilder Newcastle fans. Sissoko has made no secret of the fact he wants to leave, previously telling Sky Sports he wanted to join the "beautiful Arsenal" because he thinks he should be playing Champions League football.
What's even more remarkable is that the club appears to share his delusions of grandeur. If anything, his performance in the final for France only served as another slap in the face to Magpies fans, who must be left wondering where he'd been all season.

In fact, his best performance of the disastrous 2015/2016 campaign was on the final day against Spurs, when he perhaps sensed a chance to put himself in the shop window.
The 26-year-old has been in the north-east for three-and-a-half years, having joined from Toulouse. But nothing has summed up Sissoko's career to date quite like this little clip of him warming up for France. Note the change when he realised the cameras were on him:
The Frenchman seems to epitomise the old joke about Newcastle only turning up when they're on TV, so any potential suitors are going to need to make sure they're televised an awful lot if they're going to fork out £35million for him.
Besides, Rafa Benitez is keen to keep him at Newcastle and he's certainly going the right way about it by asking for that sort of money. Having already let Andros Townsend leave for Crystal Palace and seeing Georginio Wijnaldum linked with a host of top clubs, the Magpies will fight hard to keep hold of Sissoko.
Mike Ashley has taken the club to a place where they are not desperate for the money, and as the player still has three years left to run on his current deal, it would be a big shock if any top clubs are going to be held to ransom over the signing.
