Renee Slegers claimed the biggest win of her time as Arsenal's interim head coach as they beat Juventus 4-0 in the Women's Champions League on Tuesday. 

Since taking over from Jonas Eidevall, Slegers has led the Gunners to four wins from her five games at the helm, though their most recent result was their most impressive.

After seeing Alessia Russo and Emily Fox denied by smart stops from Pauline Peyraud-Magnin, the Gunners eventually made the breakthrough seven minutes from half-time. 

A well-worked team move saw Caitlin Foord pick out Frida Maanum inside the box, with the Norwegian remaining calm and finishing into the far corner. 

Fox again went close with an effort that crashed the crossbar, but Arsenal finally got their second when substitute Stina Blackstenius fired the ball home in the 75th minute.

Mariona Caldentey, another substitute made by Slegers, grabbed the Gunners' third before Foord sealed a statement win at the Stadio Comunale Vittorio Pozzo Lamarmora. 

Heading into Tuesday's match, Arsenal were winless across their last three Champions League away matches (D1 L2), but were worthy winners in Italy this time around. 

They accumulated an expected goals (xG) total of 2.5 from their 17 shots, compared to Juventus' 1.06 from their 12 attempts during the contest. 

In the other early kick-off taking place on Tuesday, Barcelona romped to a comfortable 7-0 victory over St. Polten, helped by a flurry of goals at the end of the first half. 

With the game level after half an hour, Ewa Pajor opened the scoring in the 32nd minute after turning home Ona Batlle's cross at Carina Schluter's front post. 

Kika Nazareth then doubled Barca's advantage six minutes later before Pajor notched her second of the game after being picked out by Ballon d'Or Feminin winner Aitana Bonmati. 

Keira Walsh then curled a wonderful effort into the far corner from the edge of the box as Claudia Pina concluded the 13-minute onslaught on the stroke of half-time. 

Barca notched their sixth from the spot after Kamila Dubcova brought down Batlle, with Pina sending Schluter the wrong way, before Caroline Hansen completed the scoring to move her side onto six points in Group D. 

Arsenal right-back Emily Fox says the chance to play in the Champions League drew her to the club as she relishes the "craziness" of the competition.

Fox joined the Gunners in January from NWSL side North Carolina Courage and has since made 18 appearances for them in all competitions.

She has proved a key figure for not only Arsenal since her move but also the United States, as she played in every game for Emma Hayes' side at the Paris Olympics, helping the team to win a fifth gold medal.

Fox has started all seven of Arsenal's matches across all competitions this season and was part of the team that overturned a first-leg deficit to beat Hacken 4-1 and qualify for the Champions League group stage.

Ahead of her debut in the tournament proper against Bayern Munich, Fox revealed the tournament played a key role in her decision to join Arsenal.

"I'm super excited. It's one of the main reasons why I decided to come to Arsenal," Fox said.

"Starting on Wednesday, playing Bayern Munich, I'm looking forward to it. All the late-night games and the craziness - I think we got a glimpse of it with all of our qualification games. I'm really excited."

Arsenal started the week with a frustrating 0-0 draw with Everton in the Women's Super League, and have the defending champions, Chelsea, next up after Bayern.

With the North London side fighting in four competitions this season, Fox has urged the team to take each game as it comes in order to get the best out of themselves.

"I think really just focusing on each and every game and not looking too far ahead," she added when asked what she had learned from the Olympics.

"I think, for example, this week we have three games in one week, which is a lot. So, I think really being present with that because it can get a little crazy if you look at it spread out and zoomed out."

Arsenal will also face Juventus and Valerenga in the Champions League group stage, with their campaign beginning on Wednesday in Munich.
