Freddie Ljungberg insists Arsenal will not get carried away after ending a nine-game run without a win at West Ham on Monday night.
Second-half goals from Gabriel Martinelli, Nicolas Pepe and Pierre-Emerick Aubameyang ensured an abysmal opening 45 minutes was a distant memory at full time with the Gunners moving up to ninth with this victory.
The 3-1 success at London Stadium was Arsenal’s first in the Premier League since a win against Bournemouth at the beginning of October, but the club’s interim boss was eager to point out there remains work to be done.
“First half we were slow, a bit lethargic and didn’t move or run, but that comes when players are low and have no confidence because you don’t do the things you need to,” Ljungberg said.
“It has been hard, but I felt ‘give it a go second half’ and it was amazing for me to see.
“You saw West Ham get a bit tired and low around the 60th and we sliced them open and played some really good football. That is how we want to play, keeping the ball well, but of course we won’t get carried away.
“We have a lot of work to do on things, but all credit to the players for how they did in the second half.”
Angelo Ogbonna’s deflected header ensured West Ham led at the break and as a result Arsenal’s players left the field to boos.
Martinelli, on his full league debut, levelled on the hour mark and Pepe curled in six minutes later.
Captain Aubameyang added a third not long after and the Gunners cruised to victory in the end, with the majority of West Ham fans leaving well before the conclusion of this London derby.
The next assignment for Ljungberg will be a Europa League tie at Standard Liege on Thursday, but he is unaware of how long he will continue in this role.
He added: “I speak with Edu. Of course we played with each other, so we try to speak because I don’t have much staff so I talk to him sometimes about football.
“I’ve been told to work on a game-to-game basis and that is what I try to do. I’ve said this is a club I love and I’ll try to help as much as I can and then it is up to them to do what they do.”
The pressure increased on Hammers boss Manuel Pellegrini, with West Ham a point above the relegation zone after another home defeat.
He insists the supporters are still with the players, adding: “The fans of West Ham always have this stadium full, with 60,000 people behind the team.
“We must improve and we need to win again here at home, but I don’t feel the fans are not behind the team.
“I think they are always behind the team and if not, maybe we play here with the stadium empty, but the stadium is always full and the fans are behind the team.”
