Ivo Pinto says Norwich City surrendered a promising position far too easily after going down to a 4-1 Sky Bet Championship defeat at QPR on Easter Monday.
The Canaries controlled much of the opening period, and deservedly went in front in the 38th minute when a rapid counter culminated in Ryan Manning putting through his own net.
However, that lead lasted barely a minute before Massimo Luongo equalised, before the hosts ran away with the contest in the second half.
"It was not good enough. We conceded easily goals, simple goals.
"We scored first when we had the game controlled, then conceded an easy goal. That gave them hope and then when they start the second half with another goal it turns everything around.
"We made our lives much harder after that. We threw it all away too easily, we practically gave them the three points."
Pinto expressed his gratitude to the club's travelling fans, with over 1,800 having made the trip to the capital.
"The supporters, once again, were amazing," City's captain added.
"They don't deserve this. If we want to achieve higher goals, we have to be better and more focused in what we want from the game.
"Our shirt carries the symbol of the city, the symbol of the county. It's a symbol for all the people who travel, week after week.
"When you wear this shirt, you have to give 100 per cent."
