Not many people would have predicted that Trent Alexander-Arnold would whip home a spectacular free-kick for Liverpool in the Champions League last night.Not even some of the most passionate Liverpool fans would have known the 18-year-old had that in his locker.But, he opened the scoring for the Reds and helped Jurgen Klopp's men to 2-1 victory over their German foes and gave them a strong advantage heading into the second leg at Anfield.One man who knows a thing or two about European nights at Anfield is the legendary Steven Gerrard, a man who now manages the under-18s for Liverpool and works as a pundit for BT Sport.Gerrard was in the studio to watch Tuesday night's encounter and went on to wax lyrical about Alexander-Arnold's performance.“It was fabulous free-kick and it’s ironic as Philippe Coutinho would probably have taken that if he was available,” said Gerrard.“It was a fantastic strike and what character he showed to step up ahead of more experienced players and take it.“I know him well, he’s going to be a top, top player and Nathaniel Clyne has to be careful as Trent is already breathing down his neck.

“He’s great professional, he’s down the academy all the time, he’s very grounded,” added Gerrard.

“He always wants to learn and improve, and I’m absolutely delighted for him and his family. It bodes well for the future.”

If the former Liverpool captain - the man that inspired that magical night in Istanbul - is saying you are going to be a 'top, top player' then endorsements don't come much better than that.

The fact that Alexander-Arnold was born in Liverpool only endears him to the fanbase more and as Gerrard rightly pointed out, Nathaniel Clyne is now going to struggle to dislodge him from the side if he keeps this form up.

Liverpool welcome Crystal Palace to Anfield in their next game and will be looking to get their first win of the new Premier League season.
