Xavi feels sympathy for Lionel Messi and his former club Barcelona following the superstar forward's switch to Paris Saint-Germain.
Messi held a tearful news conference on Sunday to confirm the end of his 21-year stay at Camp Nou ahead of completing a move to PSG on Tuesday.
The six-time Ballon d'Or winner revealed both he and Barcelona did everything possible to agree a new deal, but it was made impossible by "financial and structural obstacles".
Xavi, who won 24 trophies playing in the same side as Messi prior to departing Barca in 2015, is upset that the Argentina international was effectively forced out of the door.
"I'm just so sad for Leo," Xavi, who is now managing Qatari club Al Sadd, told The Times. "It's a pity to see he and the club couldn't find a solution.
"I know that Leo wanted to stay, but in the end it could not be sorted.
"The only thing I can say now is that I will miss him a lot. It's even hard for me to picture Messi with a shirt other than Barca's.
"It's sad for Leo, especially for how I saw him emotionally at the Camp Nou the other day, but for FC Barcelona as well."
As Barcelona get set to begin a new season without Messi for the first time since 2003, there will be plenty of onus on others in Ronald Koeman's squad stepping up.
One of those who has already made big strides in his first full campaign at Camp Nou is young midfielder Pedri, who also impressed for Spain at Euro 2020 and the Olympics.
He played more passes in the opposition half (461) than any player at Euro 2020.
Pedri's 421 successful passes was bettered by only four players, with the 18-year-old completing 65 of the 66 attempted in the semi-final loss to Italy – that one misplaced pass coming in extra time.
And Xavi can see similarities between Pedri and another Barcelona icon in Andres Iniesta, who spent 16 years in Barcelona's first team.
"Pedri is unbelievable. The kid has Iniesta's profile of a player, for sure," Xavi said.
"Watching him play at his age, doing what he does, leaves you with the only answer: he'll be great. Actually, he already is so impressive, but he can be even better."
While Spain's campaign ended at the last four stage, England reached the final on home soil before suffering a cruel defeat to Italy on penalties.
Xavi was impressed by what he saw from Gareth Southgate's side and in particular a couple of their midfielders.
"I've seen England at a fantastic level. They have absolutely everything in the squad. Well, actually they were not champions just because of a penalty," he said.
"This generation is young, physically strong but also great technically. With this group of players, they'll always be competitive.
"I can see them fighting for the World Cup, without a shadow of a doubt. They are almost there.
"I think that sooner rather than later they'll have this spark of luck you need to win trophies.
"I have also been hugely impressed by the two midfielders, Declan Rice and Kalvin Phillips. I did not know them that well, but they were superb.
"You can see a centre-back like John Stones and how he plays the ball out from the defence.
"Next to him there's [Harry] Maguire, who drives up the ball to split the opponent's pressing.
"How the full-backs and wing-backs behave for the team . . . there are details that speak volumes of Southgate's work."
Euro 2020 was a rather mixed tournament for Phil Foden, who started England's first two matches but struggled to make an impact and was largely overlooked from that point on.
"I think he is an unreal talent for a lot of reasons," Xavi said of the Manchester City midfielder. "He has an amazing work rate, but also his decision-making is ace.
"He's strong, quick, has a sense of goal, great passer and shooter... There's everything in the pack.
"I would have loved to see more game time for Foden. When you have this number of talented players, all I can think of is putting them on the pitch.
"I understand it's very tough to make changes with the squad Southgate had. There were a lot of options in his hands and only eleven could play.
"But it's a pity to see so many special talents with not much playing time."
