Brennan Johnson is excited about what Tottenham Hotspur can achieve this season with their improved squad depth.

The summer signing pounced six minutes into stoppage time to seal a come from behind success at home to Brighton & Hove Albion.

And the game at the new White Hart Lane saw them able to field both captain Son Heung-min and Yves Bissouma after their recent international commitments.

It was Son who set up fellow substitute Johnson for the last-gasp winner, which keeps Tottenham firmly in the hunt for Champions League qualification and as a big outsider in the title race.

Boss Ange Postecoglou has not had a fully-fit squad to pick from since November due to injuries, suspensions and national-team duty, but does now and has used options off his bench during the last fortnight to inspire home wins over Brentford and Brighton.

"You don’t play that well or with that togetherness if everyone isn’t on board," Johnson insisted. "Everyone is firmly on board with how the manager plays,

"At half-time he was so frustrated because we came away from the way we want to play and when we score goals like that, it is stuff we work on day-in, day-out so it’s a nice feeling because it is the rewards paying off.

"It is just excitement [in the squad]. Everyone is back and we’ve missed some really key players.

"As the manager said, now in training we’ll be doing the starters against the sub team and most times you won’t be able to tell who is starting because the quality is so high.

"We have that competition in training, there is never any bad blood, everyone gets on so well in training and we just want to push ourselves.

"It shows [here] and against Brentford, when people aren’t at it for one reason or another, it’s not down to them, but it shows the squad and the players coming on can make such a good impact."

The boss himself was full of praise for his side and especially the returning skipper, who led South Korea to the semi-finals of the Asian Cup.

Postecoglou introduced Son and Johnson with 28 minutes left and the duo combined to win it after Pape Sarr’s 61st-minute goal cancelled out Pascal Gross’ first-half penalty.

"Obviously Brighton were doing really well but they were working really hard to stay in the game and you know they’re going to get tired," Postecoglou explained.

"The fact we could bring on two attacking players who are going to be a threat, it maybe looks simple but that ball that Sonny plays, that’s a world-class player in a clutch moment.

"Even Brennan getting on the far post, we’ve helped him to do that.

"It’s not about confidence, I feel like with the squad we have for today and hopefully moving towards, we do have that ability to finish games strong, irrespective of where the game’s at.

"Maybe the nation [Son] plays for works against him but I think he’s a world-class player.

“You look at his record in the Premier League, the toughest league in the world, his goal contributions irrespective of how the team’s gone through the time he’s been here have always been right up there.

"He’s a world-class player. I thought we did well to cover his absence.

"Richy [Richarlison] obviously stepped up in terms of goal threat but to have a world-class player for the run-in is brilliant for us."
