West Ham United boss David Moyes felt his side created more than enough opportunities to win the game in their 1-0 defeat to Arsenal at the weekend.
Alexandre Lacazette scored the only goal of the game, awarded by VAR, while the Hammers were kept at bay by a mixture of good goalkeeping and wasteful attacking.
Bernd Leno in the Arsenal goal put in a man of the match performance, making six key saves for the Gunners, maintaining the relegation fears for Moyes' side.
On the defeat, he said: "We created enough chances to win more than one game today; it's maybe the most chances I've had when I've come to Arsenal [in my career].
"We did really well, but the result wasn't good. Our mistakes were up front today; we had chances to win the game, we had chances to score goals, but we didn't get them.
"We've made mistakes defensively at different times, but the chances were there today to win the game and we didn't take them.
"I've got to say that the players played very well, and I couldn't fault them. What we needed was the quality to make the difference today. When you play the bigger teams, when you get your chances, you have to take them, and we didn't quite take them today."
The improvement in performances has been there recently for West Ham, after putting in an excellent shift in the defeat to Liverpool and then comfortably beating Southampton at the London Stadium.
Moyes, though, would rather be earning points than be earning praise.
He said: "No doubt, the way we've played has been very good, but I don't want it to be a hard luck story, with people saying: 'you were a bit unlucky'.
"I've told the players I think they played well, but let's get rid of that because I'm not taking just coming in and saying 'well played' and we lose, far from it. It's the opposite. I'm saying to them: 'We can't let that happen again. We need to be more ruthless'.
"At this moment in time, I'd rather not play well and win. That's what it's about, but I thought we played well today and were very unfortunate not to take something from it."
West Ham will need to get over the defeat quickly with the games coming thick and fast in the countdown towards the end of the season.
The Hammers host Wolverhampton Wanderers at the London Stadium this Sunday, with their opponents still well in the race for a European spot.
Nuno Espirito Santo's side sit sixth in the table, two points behind Manchester United and level on points with Chris Wilder's Sheffield United.
West Ham come into the game with just one win and one draw from their last five in the league.
