A superb 2-1 away win over Juventus followed a thrilling 3-3 draw with Wolfsburg and leaves us joint top of the Group A table with the German side after two games.
In contrast the Swiss have suffered two heavy defeats and are yet to score a goal, losing 5-0 to Wolfsburg and 3-0 to Juve.
However Hayes, who guided us to the Champions League final last season, says that despite beating Aston Villa 1-0 on Saturday to earn a fifth Women’s Super League win a row, there is no room for complacency.
‘What I want to see when we get that first goal is to build on it and be more relentless instead of feeling like we have got the goal and it takes the pressure off,’ Hayes said in the pre-match press conference.
‘When you’re in a game and it’s only 1-0, you leave the other team in it. I want to see the team persist in being a bit more relentless after the first goal. It’s something we want to make more conscious in all the players.’
That focus and determination must come at both ends of the pitch.
‘You have to take pride in keeping clean sheets as a team,’ added Hayes. ‘It’s not about one player. I have seen that hunger in the team to make it extremely difficult for the opponent to create much.’
