Tottenham are certainly one of them.
Spurs are now the only team in the top-flight that have yet to make a new signing this summer.
In preparation for this drastic change, Spurs played their home fixtures of last season's Champions League and then the Europa League at the ground. They have an excellent goalkeeper and captain in Hugo Lloris.
He has done so well in getting these young players to believe in his footballing philosophy and getting them to play in such a high-intensity style both in and out of possession. With other clubs in the top six improving, it's vital that Spurs improve with them or they could find themselves falling lower in the league. They are a long shot for the title, and the task will only be harder given that they are playing their home games at Wembley this season, where they only won one in five a year ago, but it would be a glorious achievement.
Now, pundit Keown has told the Daily Mail that Eriksen is the key player for Spurs despite being an unsung hero, but suggests that he simply can't afford to have even one bad game if Spurs are to really challenge for the title. But this season seems different.
I can see this whole affair at Newcastle coming to an end soon if Rafa continues not to be backed in the transfer market.
Back in the Premier League and so it is an upgrade from David Prutton to the likes of Mark Lawrenson, Paul Merson, and Michael Owen...
But asked if Rose would have to "Google" the new additions, Pochettino pointed to the signings of Eric Dier from Sporting Lisbon, Dele Alli from MK Dons or Leicester's signing of last season's PFA Player of the Year N'Golo Kante, now at Chelsea, from French club Caen.
"I'm not sure Spurs are there yet".
Last season was Zaha's most successful, where he registered seven goals and nine assists.
Tottenham are about to start a new season without having bought a single player, yet. Second-choice striker Vincent Janssen struggled throughout the campaign to score goals. "Or Dele Alli or Kante".
But the north Londoners have not enjoyed much success at the new "Home of Football".
