On 25 July 2017, Skënderbeu reached an agreement with Chievo for the loan of Sowe for 2017–18 season.[2] The transfer was made official six days later, where he signed the contract and was assigned squad number 90.[3]
He made his Skënderbeu debut on 17 August by starting in the first leg of 2017–18 UEFA Europa League play-off round against Dinamo Zagreb which finished in a 1–1 draw.[4] In the second leg, the team held off and earned a goalless draw, with Sowe giving a strong performance, meaning that they have qualified to group stage for the second time in history, also becoming first Albanian club to successfully pass four rounds.[5]
Sowe started the domestic season on 6 September by scoring a brace in the Albanian Cup first round 8–0 hammering of Adriatiku.[6] His league debut occurred three days later in the opening day of 2017–18 Kategoria Superiore season against Flamurtari.[7] He endured 244 minutes before netting his first goal in league, which came on 23 September in the matchday 3 against Partizani, helping Skënderbeu to their first win in six matches against Red Bulls.[8] Sowe scored his first Europa League group stage goal five days later in the match against Young Boys.[9]
He was named Albanian Superliga Player of the Month in October 2017.[10] Sowe's second Europa League group stage goal came later on 23 November in the 3–2 win against Dynamo Kyiv which was their second ever group stage win.[11] He concluded the first part of the season by netting a brace in the 3–1 home win over Teuta.[12]
Sowe scored his first career hat-trick on 9 May 2018 in Skënderbeu's 4–2 away defeat of bottom side Lushnja; this win clinched the championship for the club with three games to spare.[13] He finished the league by winning the Golden Boot, netting 21 goals in 33 games, beating out his rival Sindrit Guri.[14][15]
CSKA Sofia
On 5 September 2018, Sowe was loaned to Bulgarian club CSKA Sofia until the end of the season.[16] On 31 January 2019, the transfer was made permanent, after CSKA activated his buyout clause.[17] On 1 July 2020, he was the only player to miss from the spot in the 2020 Bulgarian Cup Final, with CSKA Sofia's opponents Lokomotiv Plovdiv lifting the trophy.[18] On 10 December 2020, Sowe scored a brace in the 3–1 win over Roma in a UEFA Europa League match, though CSKA Sofia had already been eliminated from the tournament and finished in last place in their group.[19] He established himself as the main forward for the team and became the foreign player with the most goals for CSKA Sofia in all tournaments, including solely in the league.[20]
Rostov
On 16 February 2021, Sowe moved to Russian Premier League side Rostov, on a loan deal with an option to buy.[21] On his league debut for Rostov on 27 February 2021, he scored twice to secure a 2–2 away draw against the defending champions Zenit Saint Petersburg.[22]
On 10 June 2021, Rostov exercised their purchase option in the loan contract and Sowe signed a four-year contract with the club.[23]
