The England Under-21 international was caught out by a long ball in Liverpool FC’s 2-1 loss to Manchester United and 2-1 victory over relegation candidates Crystal Palace ahead of the European tie earlier this month.
Manchester City looked to target Alexander-Arnold in the first leg at Anfield but the teenager managed to tame Germany international Leroy Sane to earn rave reviews from Steven Gerrard and Steve McManaman following the 3-0 home win.
Pep Guardiola persisted with his tactic of getting the ball to Sane on Alexander-Arnold’s side of the pitch in the second leg but the 19-year-old maintained his composure to help Liverpool FC secure a 2-1 win at The Etihad.
The home grown talent provided a brilliant cross for Mohamed Salah’s 30th Premier League goal of the season in Liverpool FC’s 3-0 victory over Bournemouth at Anfield last weekend.
Oxlade-Chamberlain heaped praise on Alexander-Arnold for his composed performances in the Liverpool FC defence.
“I think he’s grown massively. In every big game he’s stood up and been counted,” Oxlade-Chamberlain told Liverpool FC’s website.
“I’m sure along the way he’s had a few mistakes but whenever I’ve seen him make errors I’ve not seen them repeated and that’s credit to him as a person and as a player.
“To make mistakes at this level, you can come in for criticism and scrutiny, [but] he’s learnt from it and got on with his business.
“He’s never scared to get on the ball and produce great things going forward and defensively he’s been outstanding.
“Over the two legs [against] Manchester City, it’s the best performance I’ve seen from anyone over two legs in such a big game.
“And even more credit to turn up today and produce again – that’s great for him going forward.
“The sky’s his limit, he can go as far as he wants to in this game, he really can.”
Liverpool FC will take on Serie A giants AS Roma in the Champions League semi-finals later this month.
The Reds are in third place in the Premier League table.
