He can keep her in a pocket where she's rendered pretty useless.
Low tiger shots = Can't slide and can't ex rhino horn through them safely because he's left in a crouching position and it whiffs. She's forced to just walk him down which can work but often doesn't if the Sagat player makes sure not to corner himself. He can punish all her specials on block with a heavy DP. Very hard matchup if the Sagat player plays it right tbh.
Bonchan vs Sako. I really do think Bonchan choked vs Kindevu at the CPTA Finals.
Abel can whiff punish Elena's cr.jab with step kick. I've had it happen to me a bit too many times. He can punish most of her specials with step kick. Abel can really have his way with her right when he gets in.
Chun can keep up with Elena's buttons, her fireball is too low to the floor to slide, can AA her fine, punish all her specials on block with ex legs, punish healing fullscreen with healing. Chun can really control the game if she doesn't let Elena get in her space and also doesn't feed Elena tons of meter by only fireball-ing.
Juri is similar, can't slide the low fireballs, Juri is able to zone her out and can't easily be locked down. Always has an answer to healing. Juri's U1 can be an instant comeback factor off of one knockdown. If Elena doesn't have meter then das it. I've played this matchup extensively with Kreymore online. Played at least 60+ matches against his Juri.
Sagat/Chun/Juri can all zone and keep Elena out. They all have different strengths in the matchup which give her a varying degree of difficulty.
I'd say
Juri 6 - 4
Chun 5.5 - 4.5
Sagat 6-4
Abel 5.5 - 4.5
This is in my opinion ofc, from what I've went against in tournament, casuals and online.
