Sky Sports is reporting the 25-year-old striker will make the move official in the next few days. Martinez is quoted as saying to Portuguese paper, O Jogo:
Only small details remain, I understand they are finalising the details in the negotiations between Jaguares and Porto, but it's not a done deal yet.
Those small details take time to resolve, but my part is done, so the most likely thing is that I join FC Porto.
Sooner or later we will be able to say I am a Porto player, but I'm still waiting. I'm eager for this challenge.
I hope everything works out as it would be very good to play for Porto. My idea is to get there and develop even more as a player.
Toward the end of April, it seemed that Martinez would be making a move to Anfield, but the rumor began running out of steam.
He had a very good season for Mexican side Jaguares, scoring 16 goals in 34 league games, adding six assists as well.
Striker is a position where Brendan Rodgers will likely be looking to add a piece or two.
The only experienced strikers in the squad are Craig Bellamy, Luis Suarez and Andy Carroll. Suarez and Bellamy are arguably better on the wings anyway.
For a team that will be playing in the Europa League, it's unreasonable to think the Reds can make it through with only three strikers.
