Arsenal have made contact with Tottenham Hotspur to understand if midfield Dele Alli is for sale, journalist Emanuele Giulianelli revealed on Twitter.
The 20-year-old was one of the most impressive youngster in the English Premier League last season.
It would not be a surprise if manager Arsene Wenger decides to make a move for the youngster.
But the Englishman made it clear in April that he "would rather quit football" rather than making a move to the Emirates.
Alli is currently in action with the English national team at the Euro 2016 Championship.
He signed a new five-year contract with Spurs at the start of the year.
