Ademola Lookman managed only one attempt and created no chances in Atalanta’s first away Serie A loss in seven months. Atalanta boss Gian Piero Gasperini insists his side must "look forward" after Sunday’s disappointing 1-0 Serie A defeat to Fiorentina. Moise Kean’s goal before halftime secured a victory for the Viola against La Dea in Serie A, as he capitalised on a poor first touch from Isak Hien in midfield, sprinting clear to score a finely executed strike. Atalanta had chances, with Luca Ranieri making crucial blocks; one was to deny Ademola Lookman, who was ultimately replaced before the hour. Fiorentina's Lucas Beltran was denied a second goal by two saves from Marco Carnesecchi, and despite late pressure from the visitors, Raffaele Palladino’s team held on for the win. The defeat ended La Dea's seven-month unbeaten away streak in Serie A and boosted the home side’s European ambitions. The Florence outfit sit eighth in the standings with 51 points, just one behind Roma in sixth.

The experienced manager suggested that it was an "off day" for Lookman and his colleagues. “We must always look forward in life, looking behind you is of no use. We have eight games to play, five of them at home, and are still competitive, ahead of many teams despite today’s defeat,” Gasperini told DAZN. “There were only four players in training the first week, which was then reduced to three when Ederson got called by Brazil. “I know everyone is dealing with international duty, but we lacked the dynamism and fitness levels to cause problems for Fiorentina. We didn’t have the energy today, we just have to put it behind us and look forward. “I actually think we did better than Fiorentina in the first half, but complicated life for ourselves with that error for the goal right before half-time. “Now we have to rediscover the focus and energy we had in the previous matches. When you have these days, you must have the strength to shelve it and get beyond that.” Lookman has now fired blanks in three of his previous four Serie A matches for the Bergamo outfit. What next for Atalanta? Atalanta return to top-flight action on April 6 when they host Lazio at the Gewiss Stadium. La Dea are third in the table on 58 points, nine adrift of defending champions Inter, who beat Udinese on Sunday.
