The Spanish club finished 6th in La Liga last season with a goal difference of just three. Their defence was comparable with the teams above them in the table but they scored just 40 goals over the 38 game season.
Mikel Oyarzabal, who plays on the left-wing, was their top scorer with 15 goals in all competitions, followed by Alexander Isak with 10.
They reached the quarter-finals of the Copa del Rey, losing 4-0 to Real Betis at home, and progressed out of their Europa group at the expense of PSV, where they were beat 5-3 on aggregate by RB Leipzig in the first knock-out round.
Their biggest signing of the summer was right-winger Brais Méndez, who joined from Celta for €14m. They also brought in striker Momo Cho from Ligue 1 side Angers, who scored four goals in 56 appearances last season, for €11m.
There is a familiar face in Sociedad’s squad though, with former City player, David Silva, a regular starter for them.
With just two games played in Spain so far, Sociedad are 11th in the table, having beaten Cadiz 1-0 away from home on the opening day of the season, before being thrashed 4-1 at home by Barcelona.
The Moldovan side finished top of their eight-team division last season, finishing the campaign with 75 goals and conceding just eight. They also won the Moldovan Cup, beating FC Sfîntul Gheorghe 1-0 in the final.
They started their Champions League campaign last season in the first round of qualifying, beating Albanian side Teuta, Armenian side FC Alashkert, Red Star Belgrade and Dinamo Zagreb to reach the group stage for the first time in their history. Being drawn alongside Real Madrid, Inter Milan and Shakhtar Donetsk, they performed admirably, finishing just three points behind second placed Inter. They beat Real Madrid at the Bernabeu, thanks to an 89th minute screamer against Thibaut Courtois.
They then entered the Europa League at the knock out stage and were beaten by Portuguese side Braga on penalties after extra time.
Their top scorer was Adama Traoré with 15 goals in all competitions, followed by Momo Yansané, who wears shirt no.99, with 12. Traoré has since left for Hungarian side Ferencvárosi TC, with Iyayi Atiemwen coming in on a free transfer from Dinamo Zagreb.
The Cypriot team finished 7th out of 12 teams last season, with former Celtic manager Neil Lennon replacing former United defender, Henning Berg, as manager with a couple of months of the season remaining. In May, they beat Ethnikos Achna FC on penalties to win the Cypriot Cup, with Lennon being sent off to the stands in extra-time.
Their goalkeeper is Fabiano Freitas, who joined them on a free transfer from Porto three years ago, and former Manchester City academy player, Brandon Barker, plays on the wing for them.
This summer, they signed Moreto Cassamá from Reims for €1.5m.
