MADRID, Oct. 23 (Xinhua) -- When Atletico Madrid travel to Borussia Dortmund in Champions League on Wednesday night, the main danger they face will be Spain international striker Paco Alcacer.
Alcacer joined Dortmund on loan from FC Barcelona over the summer after struggling to adapt to Barca's style of play, but has had no problems fitting into German club.
For a player who likes to run into space and hit the ball early, Barca's more patient build-up left him frustrated, but he is thriving with a side that gets the ball forward quickly.
Alcacer has played only 127 minutes in four games for Dortmund in the Bundesliga, but has scored seven goals, only three less than the ten league goals he netted in two campaigns with Barca.
The Spaniard averages a goal every 18 minutes in the competition (currently the best goals to minutes ratio in Europe by a long way) and also has a goal in the Champions League.
That form earned him a return to the Spain national team squad for the last round of international matches and Alcacer returned after over two years in the wilderness with two goals in the 4-1 win away to Wales.
Although he was a substitute in Spain's 3-2 home defeat to England four days later and had to watch as the English raced into a 3-0 first half lead, the striker then came on and pulled Spain back into things with his first touch as he scored a glancing header from a corner.
"It is a very important game for us," he said of Atletico game recently and although Alcacer is a slight doubt for Wednesday's game after suffering a muscle problem against Stuttgart at the weekend. If he is fit, there is no doubt who the Atletico Madrid defenders will have to keep an eye on.
