Everton manager Roberto Martinez says he hopes Romelu Lukaku, James McCarthy and Leon Osman will be fully fit for the Premier League game against Manchester United on 26 April but midfielder Steven Pienaar remains a major doubt.

The Toffees, 12th in the table, host manager Louis van Gaal's side after a recent good run of four victories and just one draw in their last five league fixtures.

And Martinez will be able to deploy record signing Lukaku even though the Belgium striker was forced to leave the pitch in the first-half during the 1-0 victory over Burnley on 18 April.

"Rom came through his role against Burnley really well with no problems. He has trained really well this week, so he is fully fit," Martinez confirmed during the press conference ahead of the game.

Meanwhile, the Spanish manager also revealed McCarthy and Osman are progressing well from respective ankle and groin injuries and are expected to be fit for the visit of the Premier League giants.

McCarthy picked up an ankle injury later in the game against the Clarets, while Osman missed it after suffering a groin problem during the previous draw at Swansea.

"Since last weekend, Leon Osman has progressed well over these two sessions so I am looking forward to seeing if he can get through the next two days' work in order to be in the squad for Sunday," the Everton manager said. "James McCarthy has also progressed well and I expect him to train today [Friday]."

However, Martinez said Pienaar, who has been plagued with injuries during much of the campaign, is expected to miss the game.

He said: "Stevie [Pienaar] is not going to be fit for today [Friday] so we are going to assess him tomorrow but it is very doubtful he will be available for the squad at the weekend.
