Adrian was disappointed to see the Hammers impressive unbeaten run finally come to an end, but hopes they can put things right against Manchester City next weekend.
West Ham suffered their first Premier League defeat in nine games as Newcastle's impressive first half display helped them come away with a 2-1 victory.
The Hammers were a different force in the second half and after Nikica Jelavic helped them back into the game, they had several opportunities to come away with a draw.
But Adrian says they were made to pay for such a poor start and were always facing an uphill struggle to take anything from the game.
Adrian said: “It is disappointing that our unbeaten run has come to an end. We were disappointed with our performance in the first half and they started the game very strong as they are fighting for their lives.
“We woke up when it was 2-0 and in the second half we started to play much better and had chances to make it 2-2. But it was too much in the end.
“We knew they would start strong as they are fighting for their position and they needed the three points.
“But we are in a good position in the table and need to keep going and maintain the form we have shown in recent weeks and show our best performances.”
Adrian could do nothing to stop Ayoze Perez and Georginio Wijnaldum firing the north east club into a two-goal lead, but showed once again why he is rated so highly with a number of outstanding saves in the second half.
But he could not enjoy the journey back to London as the Hammers suffered their first loss in the league since the defeat against Tottenham at the end of November.
He added: “It is normal when we are trying to attack and score the equaliser that they will have chances as well and we gave them space, but it was lucky for me to keep the score at 2-1.
“However it counts for nothing as we could not take any points from the game.”
Adrian is already looking ahead to the showdown clash against Manchester City at the Boleyn Ground next Saturday and hopes they can record another memorable double following the 2-1 win at the Etihad Stadium back in September.
“We need to forget this result and concentrate on the next game against Manchester City at home.
“We are playing well and have showed great performances from the start. I think it will be a great game.
“The Premier League is very tight at the moment and anything is possible. We just need to show 100 per cent from the start and not just the second half, like we did against Newcastle.”
