Alisson ends year one on Merseyside in possession of a Champions League winner's medal and the Premier League's Golden Glove award for the highest amount of clean sheets.
Best Bits: Alisson's dominant display in CL final
Kirkland, who spent part of 2018-19 as Liverpool FC Women's goalkeeping coach, was present at Melwood shortly after the 26-year-old's arrival from AS Roma to observe his sublime stonewalling qualities.
"He's brilliant," the former Reds shot-stopper told Liverpoolfc.com. "I didn't see too much of him at Roma, but when he came here I watched him closely, watched training a few times.
"This was near the start of the season and he's got better as the season has gone on.
"That is credit to the goalkeeper coaches – John Achterberg in particular – and the goalkeeper unit."
Indeed, behind Alisson throughout the European Cup-winning campaign was Simon Mignolet, who was lauded for his professionalism in serving as the ultimate back-up during a season in which he only made two appearances.
"Simon deserves a lot of credit because it's tough for him," Kirkland continued.
"But he's pushed Alisson, knowing that if he didn't perform then Simon would be back in – and the other 'keepers as well. That unit is brilliant."
