The 16th-placed Toffees will be eyeing a just a second Premier League victory in 16 matches against Marcelo Bielsa’s men.
Everton were defeated 3-1 by relegation rivals Newcastle United on Tuesday and it’s crucial they get a result against Leeds.
Here are the main talking points from Lampard’s pre-match press conference.
Gray and Mina latest
Everton’s defeat at Newcastle was compounded by two fresh injuries.
Demarai Gray and Yerry Mina both limped out before half-time.
Gray sustained a hip problem while Mina had a hip issue.
Mina , it was revealed, could be out for up to 10 weeks, with Gray’s complaint only minor.
Lampard said: “Yerry Mina is an unfortunate injury which will probably be between 8-10 weeks. It’s a strong injury around his quad.
“In the week I’ve been here, I’ve realised he’s a big leader in the group and a top player for us - a big miss.
“I was aware on the night our medical team were wary from what Yerry felt.
“Our worst fears were confirmed a day or so later.
“Demarai Gray won’t be fit for Leeds. It’s a minor knock in his hip. We’re expecting him to be fit for next week with some
“Fabian Delph is a couple of weeks away, he is making good progress.
“[Abdoulaye] Docuoure is still out. He’s one of the best midfielders in the Premier League of his type in his squad but we’ll just have to dig in until we can get some of these players back.
“I have belief in the squad and sometimes digging in is the only way, especially in our league position.
“I wouldn’t complain too much but it’s just a fact. We’re missing big players which would damage any squad.”
Mykolenko will also be unavailable again but should be back next week.
Calvert-Lewin starting chances
Dominic Calvert-Lewin was back in the squad at Newcastle, having missed the 4-1 victory over Brentford in the FA Cup.
However, the England international was left on the bench.
Lampard has previously admitted he’s being cautious with Calvert-Lewin but he’s in contention to start against Leeds.
Lampard said: “Dominic is in the squad. That’s for us to decide.
“He’s been working all week so we’ll decide tomorrow.”
