Back in September, Newcastle United won 1-0 against Swansea City away from home at the Liberty Stadium.
Jamaal Lascelles’s goal in the 76th minute proved to be the difference between the two sides in the Premier League game in Wales.
The former England Under-21 international was pleased with the win, but the youngster was not happy with his own performance against the Swans.
After the match, Hayden, who joined Newcastle from Arsenal in the summer of 2016 for a transfer fee reported by The Northern Echo to be around £2.5 million, made the following post on social networking site Twitter.
Hayden has now explained the tweet and told The Shields Gazette: “I’m realistic about these things, and I don’t think I was harsh on myself.
“I set myself high standards and I understand my game. I understand what I need to improve on.
“I just believe I’m an honest person, and if I have a good game I feel I can say I’ve had a good game If I’ve had a bad game, I feel I can say I’ve had a bad game.”
Newcastle are ninth in the Premier League table at the moment with 10 points from seven matches, just three points behind fourth-placed Chelsea.
