Poch supports Spurs' lack of summer signings
Tottenham boss Mauricio Pochettino said his side were not prepared to compromise in order to make summer signings.
Spurs were the first side in Premier League history not to bring any new faces in the summer transfer window, though they have gone on to enjoy their joint-best start to a Premier League season.
Chairman Daniel Levy told the Tottenham Hotspur Supporters' Trust that they did try to make signings but the club stand by their ultimate lack of activity and Pochettino agrees with him.
"We tried to sign but we could not achieve what we need or what we want," he said. "I think one thing is to make clear; all the coaching staff, managers, always want to improve the squad.
"We are always trying to improve our squad because football is dynamic. Every six months you need to do something to refresh. That is the history in every club.
"But if you cannot achieve what you need or want, it's common sense not to buy.
"It is easy to say that we are going to sign three players and, oh look, the people are happy because we signed.
"If we don't need the players who are available to sign then why are we going to sign them?''
Spurs are not as wealthy as the teams they are competing with at the top of the league and they are also building a new £1billion stadium.
Pochettino has hinted that their new ground - which is still not ready - could affect their clout in the transfer market.
"That can be one reason," Pochettino added. "Another reason is the philosophy or how we want to behave on the market or the idea to develop.
"The pressure of Tottenham is maybe different today and the reality is different at other clubs that are competing for the same things.
"I don't want to say names but it's like we are in the same race but we have completely different vehicles.
"But the competition is only one. When you compete you compete. You play against 11 players from different clubs."
Jack Wilshere has suffered a further setback in his bid to return to fitness for West Ham.
The former Arsenal man, long plagued by injury, underwent surgery on his ankle after a screw from a previous operation had come loose and caused pain.
Wilshere, 26, was set to return next week but following inflammation around the ankle is now sidelined until at least November. West Ham boss Manuel Pellegrini said: "Jack felt some pain the last two days so needs more time to recover."
The Chilean also revealed that he will be able to call on a fit-again Andy Carroll in just over a fortnight.
"Andy is recovering," Pellegrini added. "He started this week working, part of the warm up with the whole squad so we will see in the next week how he improves."
Marko Arnautovic is available having returned early from international duty with knee problems. Full-back Arthur Masuaku also suffered a minor problem while away with DR Congo and will be assessed ahead of today's game.
