Daniel Farke said his Norwich City side didn't make the most of their dominant spells against West Bromwich Albion.
City were eventually beaten 4-3 in a action-packed Sky Bet Championship encounter and the Head Coach said his team needed to captalise when it mattered, particularly during their dominant first-half display.
"You're never pleased when you lose the first home game and when you concede four goals so for that, we are disappointed today," admitted Farke.
"In general, I can't accuse the lads too much because the first-half was probably one of the best first-halves in the last 14 months.
"We were so much on the front foot against such a good side with so much quality. Normally the game at half-time must be done.
"The result at half-time was ridiculous. Football is never fair and you have to take your well-deserved credit.
"Mistakes cost us the goals but we still scored in the second-half. Our offensive play was good but against such a good side, we had too many individual mistakes."
City's attention now quickly turns to their Carabao Cup Round One match with Stevenage on Tuesday night.
"We have to [make changes] because at the moment there's lots of load and many players close to the starting eleven," Farke continued.
"We have lots of competition and it's not just important to rest lads, it's also important to keep the lads fresh on the pitch."
