Eden Hazard came off the substitutes' bench to score six minutes from time in a 1-0 Carabao Cup quarter-final win at Stamford Bridge, setting up next month's two-legged semi-final tie with Tottenham.
Chelsea appeared to make their interest in striker Callum Wilson public on Tuesday, prior to the tie, but Howe insisted he was unaware of complimentary comments made by Blues assistant boss Gianfranco Zola.
The Cherries boss said: "Callum's our player and very, very focused on us. I think you could see that with his performance."
When asked whether there was any scenario which could see Bournemouth sell the England striker in January, Howe added: "Not from my perspective, no."
Meanwhile, Howe was pleased with his side's performance, and he expected Hazard to make an impact after chatting to the Chelsea forward on the touchline prior to his introduction.
"He seems to have this habit of scoring against us," said Howe, after Hazard's seventh goal against the Cherries.
"He's a quality player and, again, he made the difference tonight. He has such good feet in tight areas."
