Lucescu said: “A match we should have won by three or four goals ended in a draw. I am very disappointed because today we played good football and looked quite strong in attack.
“However, we gave a lot of unnecessary gifts to our opponents. We gave them too much freedom in both cases when they scored their goals.
“It is irresponsible and totally unacceptable to play like this at Champions League level.
“We were punished for this, and it’s our mistakes that ensured we didn’t win today.”
