Scouts from Premier League side Chelsea were reportedly present at Denmark's 1-1 draw with Bulgaria in Copenhagen last night.
It is believed that they attended the game to get a closer look at Danish duo Christian Eriksen and Andreas Cornelius.
Midfielder Eriksen has been widely tipped to leave Ajax during the summer following his decision to turn down the offer of a new contract from the Dutch club, while Cornelius has scored 16 league goals for FC Copenhagen so far this season.
The form of both has alerted Chelsea, who are hoping that they can steal a march on their rivals by declaring an early interest in the pair, according to the Daily Star.
However, the report went on to claim that scouts from Arsenal, Manchester City, Tottenham Hotspur and Atletico Madrid were also at the match and they may have been interested in both players.
