Tottenham have agreed a fee in excess of £45m to sign Brennan Johnson from Nottingham Forest on transfer deadline day.

Manager Ange Postecoglou made Johnson a key target to bolster his attack before the end of the window.

Now Wales international Johnson is set to become Spurs’ ninth summer signing.

Forest academy graduate Johnson has scored 29 times and registered 12 assists across his 108 senior appearances.

Postecoglou’s Spurs side have taken seven points from their opening three Premier League games.

Johnson’s arrival would help to fill the void left after record scorer Harry Kane departed to join Bayern Munich last month.

Defender Japhet Tanganga has left Tottenham to join German club Augsburg on loan.

The deal for the 24-year-old includes a six million euro (£5.1m) option to buy if Tanganga plays a set number of games and Augsburg stay up in the Bundesliga top tier.

Hackney-born Tanganga has been with Tottenham since he was 10 years old.

In addition to going after Johnson, Tottenham are also keen to bring in Chelsea and England midfielder Conor Gallagher and Bournemouth defender Lloyd Kelly.

However, it is understood players may have to leave before they can seal those additional transfers.
