Xavi is confident that Barcelona will land their transfer targets in the next window but was unwilling to confirm whether Erling Haaland is one of those his side are chasing.
Spanish outlet Mundo Deportivo reported on Wednesday that Barcelona are growing increasingly confident of winning the race for in-demand Borussia Dortmund striker Haaland.
The 21-year-old has been linked with an array of Europe's elite clubs, including Barca's rivals Real Madrid, after scoring 80 goals in 79 games for Dortmund in all competitions.
That is a tally bettered only by Bayern Munich's Robert Lewandowski (115 goals in 97 matches) among players from Europe's top five leagues since January 2020.
Haaland has a reported €75million ($82 million) release clause that kicks in at the end of the season, although Barca's well-documented financial issues over the past year would make any deal difficult.
While falling short of confirming whether his side are looking to recruit Haaland, Xavi insisted Camp Nou is a lure for any player, despite Barca's relative recent plight.
"You say I have met with Haaland – I didn't know that!" Xavi said at a pre-match news conference previewing Thursday's Europa League match with Galatasaray.
"It's always a good time to come to Barca for any footballer. There isn't a footballer who has said no to Barca since I've been here.
"The player we want to sign, when we can talk to him, we talk to him about the game model, about the training sessions.
"If you will touch 20 balls at another club, here you will touch 40. The club, the city that is wonderful, the history of Barca ... I will try to convince any player that coming to Barca is a golden opportunity."
Speculation regarding Haaland's future will likely rumble on for a number of months yet, but Barca are hopeful of completing some transfer business of sorts before then.
Gavi and Ronald Araujo are both set to be out of contract next year, though the club are working to tie both players down to fresh terms.
"They are two very important players," Xavi said. "The club's working very well and they are a priority for us.
"It is a process. Sometimes the negotiations take a long time. We hope for the good of the club that there is an agreement."
Barca host Galatasaray on Thursday for the first leg of their Europa League last-16 tie boasting an eight-match unbeaten run in all competitions.
While the Catalans are considered the favourites of many to lift the trophy in May, Xavi believes perennial winners Sevilla are the team to beat.
"I don't see us as one of the favourites. We have never won the competition," he said. "Sevilla are more favourites than us.
"We are one of the candidates and we have to prove it on the pitch. There is enthusiasm in Barcelona. Every game at Barca is an exam, but we haven't done anything yet."
Barca have faced Galatasaray eight times previously, winning each of the past three meetings, the most recent of those a 3-1 win in the 2002-03 Champions League group stage.
