Petr Cech has revealed his delight at seeing Alexis Sanchez return to his best form in an Arsenal shirt.
The Chile international took time to get back up to speed this term following his Copa America exploits in the summer.
Six goals in three games, including a double against Manchester United on the weekend, has seen Sanchez brush aside any suggestions that he was suffering from second-season syndrome in North London.
Speaking to Arsenal's official website, Cech was quick to point out just why his teammate has needed time to fully settle this campaign.
"It's always hard for the players when you have the Copa America," he said. "Alexis won it, he was there for a really long time, didn't have much break and then came back and needed to start again.
"You could see that everybody from the Copa America had a slow start, in other teams and competitions as well.
"We're pleased that he's back with his energy, with his enthusiasm and you can see that he feels confident and with performances like that, it's great for the team."
Sanchez had previously gone eight games without a goal before finding the net three times against Leicester City nine days ago.
