: "Don’t think there’s much doubt that Alexander Isak will attract a lot of attention from clubs across Europe.
"Exceptional talent."
A journalist noticed the England legend's kind words and told the 21-year-old about them.
Isak replied: "I am not that aware of him... It's an old player working in the studio?"
The journalist then revealed Lineker was the golden boot winner at the 1986 World Cup, although the Sweden star still didn't seem too bothered.
Isak said: "I wasn't born then but I have a little bit of knowledge about him."

And during of Spain vs Poland this evening, Richards asked Lineker: "Isak, he's been talking about you, hasn't he?"
After watching Isak's press conference again, the ex-Spurs striker joked: "I said really nice things about him!
"An old player in a studio? I don't know where to go from that."
Richards was loving the banter, replying: "How does it feel when no one knows you? Now you know how I feel!"
To which the presenter laughed: "Yeah."
Lineker - England's third-highest all-time scorer with 48 goals - has been Match of the Day's main presenter since 1999, the same year Isak was born.
The former Borussia Dortmund player has been Sweden's talisman at Euro 2020 so far and is likely to start their final group match against Poland on Wednesday, June 23.
He's just enjoyed an excellent season for Real Sociedad, scoring 17 LaLiga goals last term.
And reports suggest Arsenal are interested in signing Isak this summer.
