‘There is a correlation between our physical output and our football output. You have to work hard on and off the ball if you are going to create situations time and time again.
‘I don’t think there is a coincidence that our two highest physical outputs resulted in our two best football outputs against Manchester United and Servette, so the call from us is that we want more of the same and we expect to keep pushing and improving.
‘The demands we place on the players will only increase.’
Although we have failed to beat City in eight away league games, with just two draws, we have beaten them on their home turf in the past two meetings – including last month’s 3-0 win in the FA Cup semi-finals.
‘It’s a great league record for them but not for us and it is something we have to address,’ Hayes added.
‘We have to keep building on the form and a lot of good team performances. Lots of players are playing well and scoring goals, which is what we want to see.’
City have been plagued by injuries this season and have managed two wins from six league matches so far, but Hayes said they remain a ‘top team’ full of quality despite having to do without players including Ellie Roebuck, Lucy Bronze, Steph Houghton and Keira Walsh at times during the season.
