Good news for Heather Watson. She had to dig very, very deep but has won the first set of her opening match at the Australian Open 7-6 against Hungarian opponent Timea Babos, taking a tense tiebreak 7-4.
The Gunners did not play well but the crucial thing is that they dug deep and were not beaten this time.
Wenger's side have fallen away in past seasons but performances like this one are part of the reason I think they will go the distance in the Premier League title race this time.
There are still many more big tests to come for Arsenal, but they will be there or thereabouts in May.
'A battle'
Stoke 0-0 Arsenal

Arsenal have struggled at the Britannia in recent years, their last win coming six years ago.
"It was an old-fashioned Stoke battle. They made the game very physical, the crowd were up for it, the players were up for it," said boss Arsene Wenger.
Stoke boss Mark Hughes said: "I thought it was a good football game, with both teams trying to win a key Premier League game. That's certainly what we were doing."

Back to the football now and over at the Britannia Stadium, Arsenal returned to the top of the Premier League thanks to a point from a goalless draw at Stoke.
Arsene Wenger's side missed the creativity of Mesut Ozil, who was injured, but had chances to win the game only to be denied by Jack Butland.
The draw means Arsenal move ahead of Leicester on goal difference. Stoke remain seventh.
'Thoroughly investigated'
Tennis
Chris Kermode, who heads the body that governs world tennis, rejected claims evidence of match-fixing had "been suppressed for any reason or isn't being thoroughly investigated".
But he added: "While the BBC and BuzzFeed reports mainly refer to events from about 10 years ago, we will investigate any new information."
The big news from the tennis world, though, concerns not matters on the court but off it.
Secret files exposing evidence of widespread suspected match-fixing at the top level of world tennis, including at Wimbledon, have been revealed by the BBC and BuzzFeed News.
Over the last decade, 16 players who have ranked in the top 50 have been repeatedly flagged to the Tennis Integrity Unit (TIU) over suspicions they have thrown matches.
All of the players, including winners of Grand Slam titles, were allowed to continue competing.
The TIU - which was set up to police the sport - said it had a zero-tolerance approach to betting-related corruption.

Throughout the next fortnight, there will be comprehensive coverage of the Aussie Open on the BBC Sport website.
And it's a good time to follow the tennis - Britain's Heather Watson is currently on court against Hungarian Timea Babos and it is a very close contest, 4-4 in the opening set.

The Australian Open has begun - under blue skies and scorching sunshine, just like here at BBC Sport hq in Salford - and the top seeds have made it through their first round matches with few problems.
Novak Djokovic - bidding to equal Australian Roy Emerson's record of six Australian Open crowns - eased through in straight sets, beating South Korean teenager Hyeon Chung 6-3 6-2 6-4.
It was a little tougher for defending women's champion Serena Williams, but she came through a tense match against Italian Camila Giorgi, winning 6-4 7-5.
That was a good win for Williams, who has been struggling with a knee injury and hasn't played for four months.
Monday's racing at Plumpton and Tuesday's scheduled fixture at Ayr both go ahead as planned despite concerns about the effects of the weather. But officials at Exeter say their Tuesday programme is off because the course is waterlogged.
This was a far cry from the thunderous collisions between Liverpool and Manchester United when Scousers such as Steven Gerrard and Jamie Carragher faced local products Gary and Phil Neville, as well as Paul Scholes and Ryan Giggs.
Anfield, not helped by the lack of quality on offer, was subdued and the aggression that used to be this fixture's hallmark flared only briefly in a couple of early skirmishes involving Liverpool's Lucas and United midfielder Fellaini.
This was every inch a game between sides sitting sixth and ninth in the Premier League before kick-off.
It may have even come as a disappointment to Klopp after the build-up and the history. He called these games "the salt in the soup" - this one needed an awful lot of seasoning.

United, Premier League champions?

Manchester United can still win the title ... the words of boss Louis van Gaal following victory over Liverpool.
"We have a lot of matches still to go," said Van Gaal when asked if his side could mount a late charge.
"We have to continue, which is not so easy. But we can do it because we show every week we can do it.
"The gap is seven points. We can overcome that so that's what I'm thinking about."
Blimey, bold talk from a man under serious pressure just a few short weeks ago.
Rooney clinches it
Liverpool 0-1 Man United

We're used to edge-of-the-seat, blood and thunder encounters between Liverpool and United.
Which is why this one was such a disappointment. There were times when a football match threatened to break out but alas it rarely did.
Wayne Rooney won't be too concerned though, the England skipper firing in a 78th minute winner to clinch a big win for United.
The three points led to some big talk from the manager afterwards...
Feeling depressed?

Right then. welcome to another Sportsday.
However, you may not be in the best of moods. Did you know that it is Blue Monday - officially the most depressing day of the year?
That's not something we've made up; it has been worked out by some expert team of boffins using official calculations, based on factors from the weather to debt levels, mid-January blues to the furthest point from payday.
It may also have been based on the standard of football during the Liverpool-Man United match...
