Frank Lampard is preparing for final-day Sky Bet Championship drama whatever Derby's result at Swansea on Wednesday.

Derby head to south Wales knowing victory would take them to the brink of a play-off finish given their superior goal difference over seventh-placed Middlesbrough.

A win would take Derby three points clear in sixth going into the final day on Sunday, when the Rams entertain fourth-placed West Brom and Boro visit relegated Rotherham.

Derby's goal difference is currently six better than Boro's.

"It isn't one more win [to clinch play-off spot], I have to say that," Derby manager Lampard said ahead of the trip to Swansea.

"On paper, for me, it's four points needed, because that last day is going to be tense. Anything can happen in this league, so it's not over until it's over.

"Whatever happens, West Brom on the weekend will have a lot on it."

Derby's promotion hopes seemed to be fading after only two wins in 10 games between early February and the start of April.

But County have taken 10 points from the last 12 and moved in to pole position for sixth spot by winning 2-0 at play-off rivals Bristol City on Saturday.

"I get scared of the word momentum," Lampard said. "I think momentum can make you relax when you start talking about it.

"Without a doubt we need to keep calm and focused because we need to get more points to make sure.

"We are in a nice position and the feeling is good, but we need to focus. A win puts us very, very close and then goal difference would come into play slightly."

Swansea's own play-off hopes were ended by the 2-2 home draw with Hull on Saturday.

Hull scored twice late on to prevent Swansea from claiming a sixth win in seven games.

"We've never been in there all year," said Swans manager Graham Potter.

"We've got better in the last two or three months and after the last international break we've really taken a step forward, but we haven't been good enough to get in there.

"If we'd have picked up a couple of wins here and there then OK, but the reality is we haven't done that.

"We have to look at the bigger picture and how the team has developed then make sure we keep the process going."
