Sky Sports pundit Annabel Croft tips Bulgaria's Grigor Dimitrov to beat rising David Goffin at the Nitto ATP Finals.
No. 6 seed Dimitrov and seventh-seeded Goffin are set to meet at The O2 Arena on Wednesday.
The Bulgarian beat Austrian Dominic Thiem in his opener, while Goffin outclassed top seed Rafa Nadal.
Dimitrov beat Goffin earlier this year at the Australian Open and Sofia before the Belgian ended on the winning side in Rotterdam.
Overall, Dimitrov leads their head-to-head record by a 3-1 score.
"I think the court conditions will really, really suit Dimitrov. But again, there have been question marks hanging over him finishing matches. It's a tough one to call, but I will go with Dimitrov," Croft told Sky Sports' Raz Mirza at The O2.
Goffin is coming off one of his biggest wins ever, having beat Nadal on Monday.
Yet, Croft's fellow colleague Rusedski gives the edge to Dimitrov as he thinks it is time for the Bulgarian to step and make a breakthrough.
"It's going to be close but I feel it's Dimitrov's time to step up right now even though I was really impressed with Goffin. You can give the backhand side and return of serve to Goffin, but if you look at all the other categories, I would go for Grigor," Rusedski told Mirza.
"Everybody has been talking about Dimitrov being a superstar, but now is his moment."
Meanwhile, Nadal, who has pulled out of the event due to a knee injury, has been replaced by fellow compatriot Pablo Carreno Busta.
Carreno Busta will be meeting Thiem in his ATP Finals debut.
Croft and Rusedski also predicted that Thiem is going to beat the Spaniard and clinch his first win at the event.
