Goffin has won 9/10 of his last matches on hard, whereas Gasquet has won 7/10 and Goffin is on a 6 match win streak including a tournament win in Shenzhen (another Asian tournament).
Gasquet has been on form in this tournament with a comfortable victory over Querrey, but then again Querrey has been out of form and Gasquet hasn't had to play any big players recently, except for Nadal who he lost 2-0 against.
I feel that despite Goffin being more tired after a gruelling 3 setter against Ebden, he will be able to defeat Gasquet who recently lost to Istomin and I believe will be outclassed by the Belgian.
