Marco Johnson has been relentlessly aggressive in raising preflop and taking down small pots, and has been very solid throughout. Meanwhile Alexandre Gomes has often taken down big pots with all in moves, and has certainly had some luck to be at this point. He seems prepared to gamble, while you feel that Johnson will be patient and wait for his spot to strike.
The players are still relatively deep compared to the blinds, so you'd expect a fair amount of heads up play, but the way this final table has gone so far, we could see a big pot at any moment!
