The Congo forward completed a move to the Chinese Super League, but, he revealed that before switching allegiance, he thought of his good form with the Yellow Submarine.
The 25-year-old talisman who joined the Spanish outfit from Bursaspor in August 2015 has already notched 14 goals in 19 appearances across all competitions this season.
Bakambu, the first African player to win the La Liga Player of the Month in October 2017, is eager to continue his goalscoring form in Roger Schmidt's team when the 2018 Chinese Super League begins on Sunday.
"It was not easy to make this decision because I was doing a good job with Villarreal," Bakambu told reporters.
"But now I'm here with my new team and I will do my best to score as many goals as I can."
After a lengthy transfer standoff due to the new rule made by the Chinese FA that requires clubs to pay 100% transfer tax for overseas players, Beijng Guoan general manager Li Ming disclosed how the club secured the services of the ex-Sochaux player.
"The transfer process itself was very complicated and then we had to decipher and assimilate the new rules of the federation to know how to respond,” Li said.
"We had an appropriate arrangement with the federation."
