Fabio Vieira will have been undoubtedly overjoyed when he learned that Arsenal will be facing Sporting CP in the Europa League round of 16. As a former player of Porto, one of Sporting's great rivals in Portugal, Vieira has been involved in several clashes of high importance between the two teams and will therefore likely know exactly what to expect from the Lisbon-based side.
The Gunners signed Vieira for £34million, plus add-ons, in the summer but his transition into life in the Premier League has been far from seamless. Opportunities have been limited due to the form of Martin Odegaard, with most of his appearances arriving in the Europa League.
From his 10 starting displays in four different competitions, the 22-year-old has managed two goals and three assists. In Odegaard's only league absence, Vieira stepped up to the plate with a delightful goal against Brentford and his two assists against Oxford helped the Gunners into the fourth round of the FA Cup.
