Leicester City manager Enzo Maresca has urged young defender Ben Nelson to be "more brave" and not fear mistakes after making his full league debut.
Nelson, 19, started Saturday's Championship win at Watford in place of club captain Conor Coady.
The centre-half made his first-team bow in January's FA Cup win over Millwall and had made two substitute appearances in the league before Saturday.
"It's an unbelievable feeling," Nelson told BBC Radio Leicester.
"The teams we've played in the FA Cup have all been Championship sides, but the intensity and the pressure [in the league], it's a bigger game.
