Marc Bridge-Wilkinson’s side have now racked up 14 goals and conceded only one in their warm-up games for the 2020-21 campaign.

But the Liverpool goalkeeper made immediate amends by saving the spot-kick.
The hosts soon capitalised further by taking the lead themselves with 24 on the clock. Layton Stewart’s determination allowed him to send in a pull-back from the right that invited Tom Hill to convert.
