Paul Merson believes Crystal Palace will beat Tottenham 3-1 this afternoon.
Manager Mauricio Pochettino has a few injuries to contend with as Mousa Dembele, Christian Eriksen and Mason himself are touch-and-go for the game, though he will be buoyed by new signing Son Heung-min scoring twice against Qarabag on Thursday night.
They face a stern test as Alan Pardew takes his Palace side to North London as he looks to continue his fine start to the campaign at Selhurst Park.
Their win over Chelsea at Stamford Bridge earlier this season showed just what the Eagles are capable of under Pardew, and he is looking to spring another surprise this afternoon - with Merson believing that they will claim another scalp.
Speaking to Sky Sports, Merson has predicted a 3-1 win for Palace over their London neighbours, citing that Pochettino faces the problems of coming off a Europa League game - something Spurs struggled with last season - as well as the injuries in the squad right now.
"Tottenham fans are not going to be happy with me," said Merson. "I went with them last week at Sunderland, but not this week! After playing on Thursday, going up against Palace, who are flying and were unlucky against City, just plays into Palace's hands away from home."
"It is not through bias, I just think Palace have the pace to catch Spurs. Tottenham fans are going to turn up and be begging their team to get forward. But there is no Ryan Mason, no Mousa Dembele, there are too many out."
"Spurs should have more points than they have, that's true, but they haven't and there must be a reason for that. Palace have just been to Chelsea and beat them well, and I'll be backing them for a win here," he added.
