The Everton manager says he is unconcerned by the Belgian's failure to convert from the spot against West Ham.
Everton manager Roberto Martinez has suggested that he has no qualms over keeping Romelu Lukaku on penalty duties despite the Belgian's miss against West Ham United, according to quotes published by the Liverpool Echo.
The striker took his tally for the season to 23 goals in all competitions by drilling home the opener at Goodison Park on Saturday, but saw his weak penalty saved by Adrian with the hosts 2-0 up with just over 20 minutes remaining.
That served as a catalyst of sorts for a remarkable comeback from the Hammers, but Martinez insists that he is not placing any blame on the 22-year-old for his miss.
The Spaniard said, as quoted by the Echo: "It’s not a problem. His miss was a shock. Nobody expected Rom to miss it, he is such a confident footballer.
"Penalties only get missed by players that want to take them. There’s not an issue at all. He has the support of everyone and has the quality, and I have no concerns over his confidence at all.
"He scored a fantastic goal and created another, he was a real threat throughout the game. He is still scoring goals and working really hard for the team. It’s not a worry at all."
Lukaku is enjoying the most profitable season of his career in front of goal, with his strike at the weekend taking him to 18 in the Premier League, the highest tally he has achieved in one league campaign.
The Belgian is second in the Premier League goalscoring charts behind Leicester City's Jamie Vardy, and is expected to continue on spot-kick duty for the Toffees throughout the remainder of the season.
Everton's defeat sees them lying in 12th place in the table ahead of their FA Cup quarter-final clash with Chelsea at Goodison Park at the weekend.
