Gabriel Jesus is still playing in “fear” over the knee injury that threatened to wreck his season.
The Manchester City forward marked his return to the starting line-up after more than two months out by scoring against Basel on Wednesday.
But the Brazilian looked some way short of the player he was when he burst on to the scene early last year.
The 20-year-old has suffered two big injuries during his 15 months at The Etihad and admitted the recent ligament problem plays on his mind.
Speaking after his fourth appearance back in the Champions League clash, said: “You end up thinking about the game where you got injured.
“Against Basel, I still played with some fear. There are some movements when I still have fear about getting injured.”
The return of Jesus is a big boost for boss Pep Guardiola as he looks to seal the Premier League title and conquer Europe.
But they need him to find some form as his goal on Wednesday was his first since mid-November — though he was out for seven weeks.
Jesus added: “It was only at the end of Wednesday’s game that I felt tired but it was normal because I ran a lot.
