Everton manager Roberto Martinez has reserved special praise for striker Romelu Lukaku and midfielder Gerard Deulofeu after his side's 4-0 win over Aston Villa on Saturday.

Lukaku scored twice to record his 50th Premier League goal as the Toffees brushed aside the bottom side to extend their unbeaten run to four matches and move up to seventh in the table.

Martinez admitted that he was delighted with how his team played in the victory and praised the form of Lukaku and Deulofeu.

"It was a really impressive performance," he told reprters. "I was delighted with how we carried on the attacking threat that we showed against Sunderland.

"We keep seeing a reminder of what a special talent Romelu is. Reaching 50 Premier League goals is an impressive landmark, he has incredible potential and is still only 22. You look at the other names who have achieved the landmark that he achieved today, an elite group of footballers, and I feel Rom fits into that group extremely well.

"It is a very impressive landmark but I would say that the maturity he is showing this season with the team is even more impressive than that record.

"Gerard Deulofeu has been at this level for a number of weeks now. We have young footballers with the world at their feet."

Everton next face a trip to the South Coast to face Bournemouth in a week's time.
