Alcácer had good stats at Valencia and was the main man for several seasons until his performance earned him a move to Barcelona.
However, his spell at Barca was more a step back than a step forward, since he didn't have a good experience nor did he regularly play for the side.
But Alcácer left and took off. He settled into Borussia quickly, scoring 19 goals in 32 matches in his first season. therefore he would only return to La Liga to play for Valencia.
"I know perfectly where I come from and who made who I am. Valencia gave me the opportunity and I will always be grateful", he said in an interview for 'Vamos'.
Speaking about his time at Barcelona, he said: "I wish I had the chance to return in order to enjoy it there".
