Sinisterra was desperate to leave Leeds and finally got his wish on the final day of the summer transfer window.
He completed a late season-long loan switch to Bournemouth, who confirmed they have a potential option to buy included in the agreement.
CEO Blake is thrilled to have got the deal over the line and thinks the Cherries are getting a top talent in the shape of Sinisterra.
He believes that the Colombian winger is a great addition to the squad at Dean Court.
“We’re delighted to bring Luis to the club and I have no doubt that he’ll be a superb addition to our squad”, Blake told his club’s official site.
“He’s a player that has already experienced Premier League football and has featured at the top level in Europe too, so we’re really looking forward to having him with us.”
For Leeds, losing Sinisterra right at the death in the transfer window is a big blow, but they did manage to grab Bournemouth winger Jaidon Anthony on a loan deal.
It remains to be seen what level the purchase option for Bournemouth to trigger will be set at.
