The new boss of Arsenal focused on fixing the defensive weaknesses that had become evident in the last season of Arsene Wenger.
Goalkeeper Bernd Leno was brought in from Bayer Leverkusen for £ 22.5m to challenge 36-year-old Petr Cech for the No. 1 spot.
Defensive midfielders Lucas Torreira and Mathieu Guendouzi will provide the Gunners with much-needed steel in the middle of the park.
While center Sokratis and right-back veteran Stephan Lichtsteiner bring high-level experience bags.
Upson thinks Emery has done the right thing by focusing completely on the weaknesses of his squad instead of being tempted to spill big names.

"I think they are signings that they need"
"We can all see their signings, and yes, some people might be saying, 'Well, they're not high-profile firms,'" he said. BBC Football Focus.
"But I think they are signatures that they need, that's what really impressed me.
"They have so many style players, technical quality, that's what [Arsene] Wenger was involved and recruited those players.
"But they have come out and brought players who can do simple things really well and that has balanced that team a bit more."
But former Arsenal Women captain Alex Scott had a word of warning for Emery before the start of the new season.
Londoners from the north have the most difficult start possible, facing the current champion, Manchester City (4pm) and Chelsea next weekend.
And he said Emery will have a key area to focus on to help the Gunners improve.
"It's a true baptism of fire," he said, also speaking in Soccer focus.
"Manchester City comes first in the opening game, then goes to Chelsea, and the problems of what we saw last season were for Arsenal on defense.
"They admitted 51 goals last season, and immediately have to go there and solidify the baseline."
