Spurs were all at sea right from the first whistle at Gtech Community Stadium, with Keane Lewis-Potter and Vitaly Janelt giving Brentford a deserved two-goal lead within 33 minutes.

The second of those goals came from some suspect goalkeeping from Antonin Kinsky, who was also guilty of parrying Mamadou Sangare's volley to Michael Kayode for Brentford's third early in the second half.

Spurs, who only introduced new midfielder Mateus Fernandes from the bench at half-time, could have lost by an even bigger scoreline, too, if not for Igor Thiago hitting the post from the penalty spot.

Spurs were under pressure from the first whistle, as Nathan Collins headed wide when totally unmarked and Jan Paul van Hecke narrowly avoided turning Lewis-Potter's cross into his own net.

Lewis-Potter put Brentford in front with a simple side-footed finish in the 12th minute, after new signing Sangare played a one-two with Thiago and burst into the penalty area to provide the assist.

It was 2-0 just after the half-hour mark, with Richarlison putting Spurs in trouble when he lost the ball cheaply near halfway. Mathias Jensen's long-range effort was only parried by Kinsky, and a grateful Janelt tapped into an unguarded net.

It was a similar story for Brentford's third goal, which arrived via Kayode in the 49th minute after Kinsky's failure to hold on to a stinging volley from the impressive Sangare.

Thiago missed a great chance to get in on the goals soon after, hitting the post from a penalty after Spurs substitute Rodrigo Bentancur fouled Kevin Schade from behind.

That miss ultimately proved inconsequential, though, with Mikey Moore missing Spurs' only two chances to get a consolation goal on a miserable day for De Zerbi's men.
