Kelechi Iheanacho has admitted he is yet to hit top form for LaLiga club, Sevilla this season.
The Nigeria international linked up with the former UEFA Europa League champions on a free transfer in the summer.
The 28-year-old has, however, struggled to impress at the club, failing to score in seven league outings.
Iheanacho has only started three games for the Rojiblancos.
The forward claimed he needs to put in a lot work to get back to his best.
“When you are not at your best , at your peak , then you look very tough,” he confessed.
“In general, football is not simple . Probably everyone will say that it is easy. Obviously, the way we play makes it look easy.
“But it is not because there is a lot of hard work to do, both in training and in matches.”
