Johnson-Thompson achieved the sixth global podium of her career at last year’s World Championships – and her third in as many years since recovering from a devastating Achilles rupture.
But she withdrew from the Commonwealth Games last month to focus on being in shape for the Europeans after battling to be fit following an unspecified injury.
“We would always expect with Kat to be coming in, especially with the Europeans, to try and win it,” former Olympic long jump champion Greg Rutherford said on BBC TV.
“This sport is brutal and you are never allowed to enjoy the championships if you are not winning. That’s how it is always put to us, so you never have those moments where you can go in front of a home crowd and just enjoy doing the sport.
“I feel like that’s what she is doing at the moment. It’s not about her coming here to win medals.
“She’s enjoying it rather than stressing herself for medals and that is a big change.”
Former Olympic heptathlon champion Jessica Ennis-Hill added: “She’s at the stage where there is probably going to be very few times that she comes out and is feeling great and has no niggles.
“So you have to make that decision – do I go out and compete anyway or do I step back and potentially miss a load of championships because I am not feeling 100%?”
The heptathletes will return to Alexander Stadium for the long jump on Saturday morning with Sulek-Schubert leading the way on 3,968 points.
Sofie Dokter of the Netherlands sits second on 3,944 points, while Ireland’s Kate O’Connor, who won Commonwealth gold this month, is a further 18 points behind in third with the long jump, javelin and 800m remaining.
