Pierre-Emerick Aubameyang looks “a shadow of the player he was at Dortmund” following a £55 million move to Arsenal, says Alan Smith.
The Gabon international striker became the Gunners’ record signing during the January transfer window , with a deadline day move made from Germany.
He arrived at Emirates Stadium amid much fanfare, with a prolific strike rate suggesting that he could be the man to rejuvenate Arsene Wenger’s faltering side.
Aubameyang has, however, become another victim of the malaise in north London and despite netting two times in five appearances, is struggling to show his true colours.
"Even he, in the short time he's been at Arsenal, has been affected by the mood.
"He got his goal with a little flick, but he's not the player I hoped he would be.
"I’m not saying he's a bad player, but it's a malaise through the dressing room and he's been affected."
Aubameyang was not the only player to complete a high-profile switch to Arsenal during the winter window, with former Dortmund team-mate Henrikh Mkhitaryan joining him in north London.
The Armenian has shown flashes of what he is capable of since arriving from Manchester United , but Smith believes he is another failing to produce his best as part of a team low on confidence.
He added: "We haven't seen anything from Mkhitaryan in an Arsenal shirt yet and this is when you need your big players, in an attacking sense, to get you back into a game."
"I always think with Arsenal that when they concede the first goal, like they did, then they lose their heads a little bit," said Smith.
"They can't just go back into their shape and keep it tight for 10 or 15 minutes and work their way back into a game."
