Spaniard Luque played with Suarez at Ajax and despite being involved in a publicised half-time spat during one game in Holland, the former Deportivo la Coruna, Newcastle United and Malaga attacker has no bad words to say about the Uruguayan.
"He is a good guy, and we all make mistakes,” said Luque.
"We were good friends before and after this incident and it was the only time I ever had a problem with him.
"After that game he admitted he was wrong and said sorry because that's the type of guy he is.
"He was quiet in the dressing room and kept to himself, but when he gets onto the pitch he is transformed.
"He fights for everything, he's very physical, and what happened with Ivanovic was unfortunate, but I'm sure he didn't do it with any bad intentions or in bad faith.
"Luis is a player who lives football 100%. He plays with a lot of intensity and right to the limit. We know Luis is capable of doing anything to win a game and sometimes he does things in the heat of the moment, but he is the type of player I'd always want in my team."
