Report: Serie A club prepare second bid for Hammer
Fiorentina are reported to be keen to bring the former Sampdoria star back to Serie A ahead of next season and have already seen one bid turned down by West Ham this summer.
The website quotes a well-placed source that West Ham will consider selling Obiang for the right figure this summer and Fiorentina are refusing to give up on the Spaniard by making a second improved bid later this week.
Obiang made 27 appearances in all competitions for the Hammers scoring two goals including his stunning strike in the 1-1 draw with Tottenham at Wembley.
The 26-year-old still has four years to run on his contract. Obiang is still highly-regarded in Italy after coming up through the youth ranks at Sampdoria and playing five years in the first-team before moving to West Ham in 2015.
