Less than four years ago the Canaries and Saints were both in the third tier and played one another in the Johnstone's Paint Trophy.
Norwich edged past Southampton 1-0 on Saturday as they faced up in the Premier League - somewhere their combined £65million summer spending shows they plan to stay.
City have been the more active of the sides but Hughton is open to bringing in even more before the September 2 deadline.
"What we have is a very structured recruitment policy at the club that I would like to think has served us quite well in this pre-season," he said.
"And through that if it is right to bring someone, then we will, but if we don't then I am very happy with the squad that we have got."
Ricky van Wolfswinkel, Johan Elmander and Gary Hooper have all arrived at Norwich this summer, as has teenager Nathan Redmond.
The winger capped a fine performance with the winner against Southampton, but it was another new recruit, Leroy Fer, that was named man of the match.
"I thought he had a really good all-round game," Hughton said of the former FC Twente midfielder.
"He competed very much because against a good Southampton team that you have to be solid in the middle of the park against due to the way they play and pass the ball.
"He also showed some real good quality on the ball as well.
"Leroy came back a little bit later than some of the others because he had been involved with the Netherlands Under-21s and we are learning more about him with each training session and each week passes. I thought he was very good."
Southampton's summer recruitment has involved less players but came at a cost of £35million, with Dejan Lovren, Victor Wanyama and Dani Osvaldo the three arrivals.
Saints broke their transfer record to bring in the latter two, but Pochettino suggests there is still money left to spend.
"We will see what happens from here until Monday," he said.
"There's a long time that we can make a lot of decisions, but, like us, the rest of the clubs are also looking to add to the squads, or have players leave their squads, so from here until now we'll see what happens.
"We'll see, there's a couple of areas that perhaps we need to reinforce in the side, but as I said there's a couple more days left for us to make decisions."
One department that is unlikely to need improving is the attack.
Sunderland boss Paulo di Canio last week said it was one of, if not the, best in the league - something Hughton agrees with.
"I think that's right, certainly with what they have in the two front players," the Norwich boss said.
"I suppose the challenge for the manager is getting the right combinations - that is always the case.
"But they have so much fluidity in the front four players, whichever they are.
"They will be a threat for most teams this season and I think they are the type of team that will play the same type of game away from home as they do at home."
Saints failed with numerous chances to score at Carrow Road and have yet to find a way of harnessing the talents of Rickie Lambert and record signing Osvaldo.
"I think it's normal that they weren't able to link up well," Pochettino added.
"It takes time for a player to gel, to get into a squad.
"It's their first game together and he needs time, he needs effort to actually start to play well with Rickie, so it will take time."
