Sergi Roberto Carnicer (Catalan pronunciation: [ˈsɛɾʒi ruˈβɛɾtu kəɾniˈse], born 7 February 1992) is a Spanish professional footballer who plays for Serie A club Como in Italy.

[9] On 27 April of the following year he made his first UEFA Champions League appearance, coming on as a substitute for David Villa in the last minute of a 2–0 away victory over Real Madrid in the competition semi-finals' first leg.

[11] His first start for the main squad came on 6 December of that year, against BATE Borisov in the Champions League group stage, as manager Pep Guardiola rested all his starters for the upcoming El Clásico: in the 35th minute, he opened the scoring in an eventual 4–0 home win.

[17][18] In two consecutive matches against Athletic Bilbao in January 2016, one in the league and another in the Spanish Cup, he featured on the other flank in the place of injured Jordi Alba,[19] going on to play in as many as seven different positions.

[21] On 8 March 2017, Roberto scored the final goal in the 95th minute as part of a decisive 6–1 home victory against Paris Saint-Germain in the second leg of the Champions League round-of-16, making Barcelona the first club to overcome a four-goal deficit in the competition.

[24] In injury time of the first half of the fixture with Real Madrid on 6 May 2018, Roberto was shown a straight red card after punching Marcelo, in an eventual 2–2 home draw.

[35] On 24 September, as the newly promoted side, coached by his former Barcelona teammate Cesc Fàbregas, won 3–2 at Atalanta, he assisted Gabriel Strefezza in the first goal after backheeling a pass from Ignace Van Der Brempt.

This versatility, combined with his pace, strength, rigorous work rate and accurate passing earned the praise of the manager: "In a team like ours, except in goal, he could play in any position, it's no surprise.
