Deulofeu signed with Everton on a season-long loan deal at the start of the season and Martinez is keen to keep the 19-year-old at Goodison Park for the 2014-15 Premier League campaign too.
"I think he was taken out of context. The interview was on Catalan radio and the question was 'would you like to play one day for the Barcelona first team?" Martinez told the Liverpool Echo on Monday. "The answer is going to be, as a Barcelona player who has been there since he was eight, yes, because that's his focus and wish for the future.
"But the interview does not imply he definitely will not remain here next season. He never said he's not enjoying his time at Everton. He has loved the test in the Premier League and being with us."
Deulofeu has made 15 appearances in the Premier League so far this season, scoring twice, and Martinez is convinced the teenager has benefited from his time in England.
"We all share the view that nobody will be prouder than every Everton fan and person connected with Everton to see Gerard Deulofeu's career has improved here," Martinez said.
"We've benefited from having his talents with us. Our agreement with Barcelona was to have him for one season though and that's where we are."
