LONDON - Arsenal manager Arsene Wenger hailed the speed of Alexis Sanchez's adaptation to the English Premier League after the Chilean forward's last-gasp winning goal sank top-four rivals Southampton.
Sanchez, a £30 million (S$62 million) signing from Barcelona, netted his 14th goal of the season in the 89th minute of Wednesday's game to earn Arsenal a 1-0 win that sent them to within two points of the Champions League spots.
Sanchez, who has been the talisman for Arsenal in the opening four months of the campaign, received the accolades of his manager after his strike lifted the North London club to sixth place.
"He was one of the players who had to dig deep today (Wednesday), but he has such a desire to fight that he always finds something special to get the goal," Wenger said.
"It's difficult to find examples of people who have settled in so quickly. My memory is not perfect, but I can't think of a quicker one.
"We're in December and he arrived in July. When you look at the number of goals and the impact he has had in the team, it is fabulous."
Wenger was on the receiving end of boos from Arsenal fans when he replaced Alex Oxlade-Chamberlain with Olivier Giroud in the 65th minute.
But the relief at Sanchez's last-gasp strike was palpable as Arsenal maintained the momentum sparked by victory over Borussia Dortmund in Europe, and nurtured by a gritty away success at West Bromwich Albion.
Wenger added: "For us, it was important to win because we lost our last home game (to Manchester United). We had the right attitude, a good solidarity and focus, and it's a good basis.
"But you could see that the confidence within the crowd was a bit nervous. At times, it transmitted to the players.
"We did not have our usual fluency in the game, but it's important that you can win a game when that is not perfect."
Southampton remain third despite back-to-back losses, having gone down 3-0 at home to Manchester City on Sunday. The St Mary's outfit also have a growing injury list ahead of the visit of Manchester United this Monday.
But Wenger tipped the south coast club to recover from their blip and be in the hunt for a top-four finish come the end of the season.
"There is a long way to go, but I think they are top-four contenders," said the Frenchman.
