The Gunners recently drew 0-0 with Stoke City and were praised for their new found mental strength.
The Gunners are currently top of the table after 22 games of the season, having managed to survive the busy Christmas period despite a raft of injuries to key players.
Their last game saw them draw 0-0 at Stoke City; with many saying they showed the type of mental strength and determination that Champions are made of, as they had to fight hard for the point.
It had often been labelled at Arsene Wenger’s side that they were lacking the mentality to be title winners in season gone past but that looks to have changed, and Walcott says their mental strength is the best he’s ever seen it at the club.
“We felt from the start we were up for the fight, physically,” he told arsenal.com.
“It’s a shame that we couldn’t get the result we desperately wanted but it is an improvement from previous performances [at the Britannia] and we have got to be proud of that point.”
“The mental strength in our dressing room is the strongest it has ever been. When you have the likes of Petr Cech coming in as well, he only enhances that.”
Walcott's point about Petr Cech is certainly a shared one, with the goalkeeper having proved to be fantastic addition since his move from Chelsea in the summer.
He has been a major part in their change in mentality, especially defensively, with the Gunners currently holding the joint third best defensive record in the league.
That is likely to be key to their title hopes come the end of the campaign, and Arsene Wenger will be hoping they can continue to show that new found steel in the second half of the campaign.
