If the manner of the wins over Ipswich Town and Atletico Madrid pointed to Andoni Iraola making his mark at Liverpool, Saturday’s dismal stalemate with Fulham laid bare the issues he is grappling with.This was an error-strewn performance lacking in redeeming qualities. Liverpool were flat, careless and disjointed. They were outplayed for significant periods by a team who had lost all three of their Premier League matches before their visit to Anfield.Iraola felt that fatigue had heavily contributed to standards slipping alarmingly after the energy expended to beat Diego Simeone’s Atletico in midweek. Intensity was conspicuous by its absence.“There was a lack of freshness definitely — we cannot hide it,” Iraola told reporters post-match.“It’s the worst turnaround in terms of 60-something hours between the games, but this is going to happen more times. We have to adapt.“These kind of games you need to win sometimes with a set-play, a shot from the edge (of the box), a moment of brilliance from an offensive player — but we didn’t have that. It’s the first game since I’ve been here that we’ve had problems creating chances.”Alexander Isak, who squandered a glorious late chance when he glanced a header wide from Dominik Szoboszlai’s corner, looked jaded. The same goes for Bradley Barcola, who understandably needs time to get up to speed following his big-money move from Paris Saint-Germain.But Liverpool’s most concerning weaknesses on show against Fulham had nothing to do with weary limbs. Take the left-back spot, where the recalled Kostas Tsimikas was so poor that he was taken off at the break. In truth, the Greek defender was lucky to have stayed on that long, having won three of his eight duels (38 per cent) and completed just 20 of his 31 passes (65 per cent).Andoni Iraola sums up what most of Anfield felt during the 0-0 draw (Peter Byrne/PA Images via Getty Images)It was the cheap option to bring back Tsimikas after a season on loan at Roma to provide cover for Milos Kerkez following Andy Robertson’s exit, rather than dipping into the transfer market. It could end up costing Liverpool.
