North London rivals Arsenal and Tottenham Hotspur may reportedly go head to head for the signing of £50m-rated Everton centre-back Michael Keane.
The 26-year-old has statistically been one of the best in his position during the 2018-19 Premier League campaign, outranking all but Liverpool's Virgil van Dijk for key defensive measures.
Keane's form has seen him regain his place in England's senior squad, playing a full part in the wins over Czech Republic and Montenegro this month.
According to the Daily Mail, Everton could face a battle to keep him at Goodison Park in the summer as Arsenal and Tottenham are lining up bids.
Both teams are said to have sent representatives to watch the defender during the Toffees' 2-0 win at West Ham United on Saturday.
Tottenham are after a long-term replacement for Toby Alderweireld and Jan Vertonghen, who are both reaching the end of their contracts, while Unai Emery has admitted that he wants to strengthen his backline ahead of next season.
