Tottenham Hotspur’s summer transfer plans took a twist as the club opened negotiations over a move for Sporting Lisbon midfielder Bruno Fernandes.

Manchester United have been tracking Fernandes this summer, but Spurs officials have flown out to Lisbon to try to set up a deal.

Tottenham are still interested in Real Betis midfielder Giovani Lo Celso, who has been one of the club’s primary transfer targets, and had shelved interest in Fernandes to pursue the Argentine.

But having so far failed to agree a fee for Lo Celso, who Betis value at £68million, Spurs are now making serious enquiries over Fernandes as they look to strengthen manager Mauricio Pochettino’s squad ahead of the closure of the transfer window next Thursday.

Tottenham hope to be able to land either Fernandes or Lo Celso for around £55m, although Sporting have previously quoted a fee as high as £70m for Fernandes.
