Argentine striker Sergio Aguero is in line to make his long-awaited La Liga debut for Barcelona on Sunday and the club will hope his presence in the team can provide a much-needed boost following a disappointing start to the season.

Aguero, 33, joined Barca on a free transfer in the summer after a trophy-laden decade with Manchester City in which he became the fourth leading scorer in Premier League history and struck 260 times to become the club's all-time top scorer.

But the excitement of his arrival was quickly overshadowed by Lionel Messi's shock departure in August, which was soon followed by Aguero, a close friend of the former captain, injuring a calf muscle. He resumed full training this week and is expected to be on the bench when Barca host Valencia looking to respond to their 2-0 defeat at Atletico Madrid before the international break.

Aguero's return comes at an ideal time for Barca, who have one win in their last six games in all competitions and failed to score in four of them to turn up the pressure on manager Ronald Koeman.

Barcelona failed to have a shot on target in each of their 3-0 defeats in the Champions League to Bayern Munich and Benfica respectively and only tested Atletico keeper Jan Oblak twice in their loss to the champions.

Aguero meanwhile, has his own point to prove after struggling with fitness problems for most of the last 12 months, in which he had to endure numerous setbacks including two knee injuries and a long period out due to coronavirus.

He also expected to be playing with Messi and in a side challenging for the title rather than in one that is ninth in the table and bottom of their Champions League group.

"The majority of players want to wear this shirt, whether Barca are doing well or badly. I arrived with the expectation of playing with Leo and that a big team would be assembled, which was the club's aim," Aguero told newspaper El Pais on Thursday.

"But you can only be a starter when you are playing well and helping the team. That's what I'm thinking about, helping the team with a goal every time I play regardless of the changes the team has undergone, among them Leo's departure."

Elsewhere in La Liga, Real Sociedad have the chance to go three points clear at the top when they host Mallorca on Saturday.

Leaders Real Madrid and second-placed Atletico are not playing after their matches were postponed due to La Liga's rift with Fifa over South America's World Cup qualifiers.
