Arsenal boss Arsene Wenger believes his side can still win the Barclays Premier League title.
The Gunners have had a nightmare fortnight, losing in the Carling Cup final against Birmingham before falling to Barcelona in the Champions League last 16.
Defeat against Manchester United in the FA Cup yesterday leave the clubs fighting for only one trophy now, but the title has always been the main priority for the Emirates outfit.
"It's important we respond very quickly. We go to West Brom on Saturday, we will see the first signs of how we recover," said the Arsenal boss.
"I believe that we can do it. It is a good test for us now, to show that we can regroup, show our mental strength and respond quickly."
Chasing a first title since 2004, Wenger recognises the crucial nature of a clash against United in May, a match which could prove to be pivotal with regards to the destination of the league.
Whilst there is likely to be many more twists and turns in the weeks ahead, Wenger and Ferguson would be poised to go head-to-head in one of the most important English matches in recent times.
"The Manchester United game [in the Premier League] is only important if we win our games before that," the Frenchman continued.
"I am convinced that if that game is decisive, we have a good chance to do it at home."
