The Hammers reportedly agreed a £26million transfer fee with the San Siro outfit for the Colombian international earlier in the summer and have been heavily linked with him throughout the window.
But the 29-year-old was seemingly unconvinced by a move to the Olympic Stadium, with a notable lack of progress since reports of an agreed fee first emerged.
And the 5 foot 11 front-man has now revealed that he’s committed to staying on with Rossoneri for next season, essentially ruling out West Ham’s chances of a summer swoop.
He told AC Milan’s official club website: “So many things have been said. There were some teams that wanted to sign me, but in the end I have decided to stay and I am happy with my decision. Now I just want to work to be ready for the kick-off of the season.”
Bacca was in fantastic form last season, netting 18 times during his debut Serie A campaign after signing from Sevilla in summer 2015.
The former Club Brugge star won consecutive Europa League titles with the La Liga outfit, bagging 49 goals across two campaigns.
