Sergio Aguero N/A - On for Dest – to a huge roar - for his first appearance in a Barca shirt. From signing for the Catalans until now wasn’t as he hoped it would be, but the Argentine can be a huge influence at a club short of players of his quality. Fans hoped for a goal, but three points will suffice. Reuters
BARCELONA RATINGS: Marc-Andre ter Stegen 7 - Beaten by a fifth minute Gaya rocket and kept busy by the lively Valencians. Top save from Guedes at the start of the second half. Beaten by a Soler shot after 53, too. His post wasn’t. Getty
Sergio Roberto 6 - Busy opening for Mr Versatile who was played at right back in a 4-3-3 which shifted formation when Barca were not in possession. Getty
Gerard Pique 6 - The unpredictable and enigmatic Guedes tested the 34-year-old, as did Soler’s runs, but Pique’s experience and meant his positioning was effective. AFP
Eric Garcia 6 - Started in central defence in the first of three huge home games for Barca with a Champions League match against Kiev followed by a clasico next weekend. Spoke about others rather than himself after the game. Good team player. EPA
Jordi Alba 7 - Dangerous cross towards Dest after nine minutes as Barca tried to equalise. No player came close to his 109 touches, which again showed how vital the 32 year old is – even without his old attacking foil Lionel Messi. EPA
Frenkie de Jong 7 - In a better Barca team, he’d be more attacking but the Dutchman had to defend deep against a dangerous Valencia. Brilliant pass to release Dest. Reuters
Sergio Busquets 7 - Booked for a late tackle on the influential Soler which drew a roar from the crowd. At least there were fans since Camp Nou was back to allowing 100% – though only 47,317 showed in the 99,000 capacity venue. Reuters
Gavi 6 - Seventeen-year-old man of the moment played on the left. Heavy challenge on Soler after 20 minutes earned him a booking, but key in Barca having control and 60% of possession in a vital win. Getty
Ansu Fati 8 - Back after a year long injury and equalised with a low curling shot after 13 – a superb goal. Wonderful. Fouled for a 39th minute penalty – which Valencia’s players disputed. Fans sang his name and want him back for more. He’s been missed. EPA
Memphis 9 - Played centrally and set up strike partner Fati for the equaliser. Confident in build up play and hit a 29th minute free-kick so high it flew into the second tier. Struck a perfect 41st minute penalty to put his side ahead. Man of the match and exhausted by the end. Getty
Sergino Dest 8 - More advanced role than normal on the right – as an attacker rather than defender, though he had to get back too. Set up Coutinho for the third – his key passes are vital. Becoming a bigger influence for the Catalans. Reuters
SUBS: Phillippe Coutinho 7 - On for Fati after 59. The Brazilian scored the third after 85 minutes and looked absolutely delighted – as did his teammates. His team needed that goal, but not as much as the midfielder who has had the bumpiest ride since leaving Liverpool. Nobody had more than his three shots – and he was only on the pitch 33 minutes. EPA
Oscar Mingueza 6 - On for Sergi Roberto after 71. The defender seldom starts and relations with coach Ronald Koeman could have been better, but he’s a big talent. AP
Nico González - On for Gavi after 71, the 19-year-old midfielder is another youngster getting minutes from Koeman. The son of the former Deportivo La Coruna midfielder Fran did well. Reuters
