Former Tottenham Hotspur manager Tim Sherwood says a defender and a striker should have been signed during the summer transfer window.
Spurs enjoyed a positive start to the new season winning two of their first three games but the lack of offensive power means they might miss out on a top-four finish.
"I've been encouraged with the start, obviously Daniel Levy's backed a manager again," Sherwood told talkSPORT.
"Say what you want about Daniel Levy but he backs them in the transfer market and makes sure they get the players, and he's gone out there and signed six players.
"I don't know much about Stambouli, the boy from Montpellier.
"Fazio is an experienced Argentinian defender who won the Europa League last year with Sevilla. [Pochettino] would know him very, very well.
"I think that's what they need, they need some cover there at centre-half just in case Younes [Kaboul] gets injured and I would say they're probably one short of a striker to really challenge for top four."
Tottenham Hotspur were just a point away from qualifying for the Champions League play-off two seasons ago but ended last season in sixth place, ten points from a top-four finish.
And according to Sherwood, this season will be very difficult to qualify for Europe's most prestigious competition.
"It doesn't get any easier, every year, as much as you try," added the manager.
"Obviously the emergence of Liverpool has put everybody's nose out, because there's another spot which looks like it's going to be taken.
"Brendan [Rodgers] has done a great job there.
"Obviously he's built a philosophy there, took a step back and decided what they were going to do and they've moved forward and got the correct man to be able to apply that.
"Obviously Man United, now, are unrecognisable to any Man United side we've seen over the last 10 years.
"They would never, ever sell their academy players who were playing in the side but now they've decided to do that and they're going out and buying the very best players from all over the world.
"It's very exciting for the fans but, for the long-term future, of the club, I think it hurts them."
