Botafogo striker Matheus Nascimento is set to stall joining Nottingham Forest.
Forest are chasing the 19 year-old attacker before the summer market closes at the end of the month.
They've offered £15m for Nascimento, but he wants to stay with Brasileiro Serie A leaders Botafogo and help them win the title.
As such, any deal is likely to wait until January, says The Sun.
Nascimento is a Brazil U20 international.
