Hull City boss Steve Bruce says they'll immediately reinvest the money raised from Shane Long's sale to Southampton.
Despite only joining the Tigers in January, Long joined Southampton on Thursday for a fee reported to be around £12million.
"We got what, in our opinion, was a fabulous offer," said Bruce. "It happened so quickly. This time last week I would never have envisaged us being without him."
Long played in both of Hull's Europa League qualifying matches this season and now the FA Cup finalists have promised to use the funds received from Southampton to strengthen their squad.
"We will invest that money into the squad to make it bigger and better, and we'll be looking to find a replacement," Bruce added.
"We've got irons in the fire. I'd like at least another three players to come through the door. The money that we got for Shane will allow us to do that."
