Varela made his debut for Porto off the bench in a draw against Arouca before starting in a 1-0 victory over Estrela, and Conceicao stuck with him for their Champions League group-stage opener against Shakhtar Donetsk. The Dragons stormed to a 3-1 win over the Ukrainian champions, and Varela played the full 90 minutes, only to face criticism from his manager in the days that followed.
Speaking on the integration of Varela and fellow new addition Ivan Jaime, Conceicao said: "They have to understand some of the ideas I have. I would say they have a lot to improve." The Porto manager's words had the desired effect, though, as Varela nailed down a spot in his starting XI with a string of stellar performances to help the team fight at the top of the Primeira Liga and qualify for the Champions League knockout stages as runners up in Group H behind Barcelona.
Varela eventually opened his goal account for Porto in January, showing great composure to capitalise on a defensive error and round two players before tapping into the net, finishing off a 5-0 rout of Moreirense. He produced a brilliant first-time finish from the edge of the box the following week as Porto saw off Farense, leaving Conceicao delighted with his progress.
"He has a good arrival, a good shot, he defines well - both in the short and long pass. He is also a player with quality and, in that sense, there has been an interesting evolution, especially now that I am asking a little different things of him," the Portuguese coach told a press conference.
Porto then turned their attention to the first leg of their last-16 Champions League tie against Arsenal at the Estadio Dragao, which saw Varela properly introduce himself to fans across Europe. Porto secured a massive 1-0 victory thanks to a late strike from Galeno, but it was Varela that walked away with the Man of the Match award.
Varela recorded more ball recoveries (five), interceptions (three) and passes in the opposition half (11) than any other player, running himself into the ground while also showing great technical quality on the ball. Porto would go on to exit the competition on penalties after a tense second leg in north London, but they did so with their heads held high, and Varela's stock has only continued to grow.
Porto slumped to a disappointing third-place finish in the league, but can still salvage silverware in the form of the Taca de Portugal, if they beat new champions Sporting in the final. The question is: will that be Varela's send-off game now that Liverpool and others are hot on his tail?
