Javier Hernandez has refused to rule out the possibility of leaving Bayer Leverkusen before the close of the transfer window.
The Mexico international scored 17 goals in 28 Bundesliga appearances for the club following his deadline-day move from Manchester United last year.
Before making the move, Hernandez spent a season-long loan at Real Madrid.
"You never know what happens in football," Hernandez told Kicker. "In years gone by I have left my club on the last day of the transfer window. I thought I would stay in Madrid and I thought I would stay in Manchester but I joined Leverkusen in the end.
"It motivates me if I am a theme for other clubs."
Hernandez has two years remaining on his contract at Leverkusen.
