Former Tottenham Hotspur captain Ledley King believes the additions of Victor Wanyama and Vincent Janssen will act as a "big boost" for the club ahead of the new Premier league season. Mauricio Pochettino has only made two signings this summer but without any significant departures looks set to begin the campaign with a significantly stronger squad.

Wanyama became the first addition after arriving from Southampton for £11m ($14.51m), according to The Guardian, before Janssen moved to White Hart Lane for £18.8m, according to Sky Sports, from AZ Alkmaar following a lengthy spell of negotiations. A clutch of youth players are left in the club, meaning Pochettino's team are well-placed to improve on their third-place finish last term.

Last season's top four place dictates that Tottenham will have to juggle their domestic demands with the Champions League, meaning Spurs will require an expanded squad in order to be able to fight equally on four fronts. King is therefore impressed by the work conducted this summer and says the subtle changes will make a difference.

"I'm pleased with those two signings," he told Press Association Sport, according to The Evening Standard. "Another attacking option was very important and Janssen has a great scoring record from playing in Holland. Wanyama I've seen many times and I've been very impressed by him. He's a bit like Eric Dier, you don't see all the good work he does.

"I saw him for Southampton at White Hart Lane last season and he was one of the best players on the pitch. The manager knows him well so it's no surprise he's gone for him. I think both players will be a big boost to the squad."

Janssen finished as the highest scorer in Eredivisie last term with AZ and will provide support for Harry Kane, who netted 25 league goals for Tottenham last term. Kane was expected to be among the stars of the European Championships but looked heavy-legged throughout England's campaign – but King is not concerned.

"I'm entirely confident in Harry getting back to his best," the ex-Tottenham defender added. "He's the kind of player who doesn't seem to suffer from a lack of confidence, he always has the utmost confidence in his ability to score goals.

"It wasn't a tournament where he was missing lots of chances, he just wasn't able to find the positions that he normally does. I've got no worries for Harry, he'll be back, he'll be hungrier as a result and he'll be looking to prove people wrong again. He did that last season when people were asking if he was going to be a one-off and he can do it again."
