Giulian Biancone scored his first goal for Nottingham Forest as their pre-season schedule began with a 3-1 defeat.
The Reds took the lead against Coventry City at the Pinatar Arena in Spain. But the Sky Blues responded before the interval and then took the lead in a second half which saw a youthful side fielded by boss Steve Cooper.
In searing heat, the game took a while to get going, with not much by way of action in the opening minutes. Forest gradually began to hit their stride, though, and started applying some pressure.
