The Daily Mirror reports that both Spurs and the Gunners had representatives watching Keane, 26, in Everton’s 2-0 win at West Ham United on Saturday, and suggest that the Toffees could face a £50 million offer for the England international in the summer.
Keane joined Everton in July 2017 from Burnley for roughly £25 million, and after a difficult first season, has fared far better under Marco Silva this term.
The former Manchester United prospect has featured in all but three of Everton’s 32 Premier League games this campaign, and his superb form has seen him regain his place in Gareth Southgate’s England squad.
With Spurs potentially set to lose Toby Alderweireld this summer, and Jan Vertonghen, 32 this month, in the latter stages of his career, Mauricio Pochettino is likely to be in the market for reinforcements in central defence this term.
Arsenal, meanwhile, have been notoriously porous at the back at times under Unai Emery, and Keane may be regarded as a player who could solidify their back line.
Although with Everton set to let Phil Jagielka, 36, leave this summer, and Chelsea loanee Kurt Zouma likely to return to West London given their transfer ban, Keane, Yerry Mina and Mason Holgate could well be the only senior centre-halves on the club’s books, so a hefty fee would surely be demanded to let Keane go.
