Andoni Iraola’s first game as Liverpool head coach at Anfield ended in a 3-2 loss to Monaco from France’s Ligue 1.He selected a strong starting XI for Sunday’s friendly and his side raced into a two-goal lead before the half-hour mark, as Alexander Isak opened the scoring on 16 minutes before Florian Wirtz tapped in a second.Monaco halved the deficit just before half-time when Aleksandr Golovin converted a penalty, which he won when he was fouled by Virgil van Dijk. Mika Biereth equalised 11 minutes after the restart, scoring at the second attempt after being denied by an excellent Giorgi Mamardashvili save.The intensity dropped in the second half as both teams made a string of substitutions before Liverpool’s set-piece problems from last season raised their head again as they conceded an 88th-minute winner; Paris Brunner heading in from a corner.Andrew Jones analyses the main talking points.Are we starting to see the Isak-Wirtz link Liverpool hoped for?Florian Wirtz scores Liverpool’s second goal against Monaco (Naomi Baker/Getty Images)If Liverpool can see this version of Isak and Wirtz consistently during the upcoming season, there is plenty to be excited about.Last summer, they invested more than £225million ($303m) combined in these two players, who they thought would lead their attack into a new era. For differing reasons, neither had the debut season that anybody at Anfield would have hoped.Under new head coach Iraola, though, it is so far so good.Their first outing of pre-season, in the opening 45 minutes against Leeds United in Chicago last Sunday, was a real positive as they contributed to Liverpool’s best half of football on the three-game tour of the United States, and as a partnership it looked like a connection had already been established as a No 9 and a No 10.Their performances against Monaco today were another positive step forward, and both looked like the players Liverpool thought they were buying last summer. They were sharp and nearly combined in the seventh minute when they traded passes in the Monaco area before Wirtz’s shot was saved by Lukas Hradecky.They continued to cause problems throughout the first half, with Wirtz finding plenty of space in between the lines and Isak constantly posing a threat in behind, as well as being involved in build-up play.Isak gave Liverpool the lead when he received a pass from Ryan Gravenberch, who had played a neat one-two with Dominik Szoboszlai, and finished calmly into the bottom left corner from the middle of the area. Wirtz’s bright play was rewarded when he scored from close range after a goalmouth scramble to make it 2-0, with Isak picking up the assist.Their threat continued in the second half, before they were both substituted just before the hour.How many transfers do Liverpool actually need?Jon MackenzieHow did Munoz do in his first Anfield appearance?Liverpool supporters have had to wait some time to see summer signing Victor Munoz in action, but they finally got their first glimpse of him against Monaco.
