You can view today’s video above when the biggest talking point was Mohammed Kudus. It's been reported that Arsenal are monitoring the West Ham attacker with Leandro Trossard attracting interest from Saudi Arabia. Kudus has excelled since moving to West Ham from Ajax but it's understood that the Hammers would hold out for close to €90 million to sell their prized asset. 

Elsewhere, Barcelona and Bayern Munich are contemplating activating Diogo Costa's €60m release clause. Both European giants are in the market for a new goalkeeper and the Portugal No.1 is widely regarded as one of the best in the world. Randal Kolo Muani's move to PSG hasn't worked out with the French champions open to loaning the striker out in January with a number of Premier League clubs expressing an interest? And what next for Neymar? The Brazilian is out of contract at the end of the season and he's been linked with moves to Santos, Barcelona and Inter Miami.
