Millwall boss Kenny Jackett admitted his side got a taste of their own medicine at Ipswich on Saturday.
The Lions travelled to Suffolk on the back of a sparkling 13-match unbeaten run which lifted them into the play-off places.
But they came unstuck at Portman Road as lowly Ipswich ran out convincing 3-0 victors, and will now look to get back to winning ways against Leicester next weekend.
"Games like that can go either way very easily - but we have been winning those type of games lately," said Jackett.
"We have been the ones with the dominating centre-backs and we have had the forwards that have been causing all the problems.
"Ipswich found an intensity with over 17,000 people behind them and we needed that in the first half to get something to build on.
"We kept going and kept battling but we couldn't quite find the breakthrough."
The League are now awaiting the outcome of this week's make-or-break High Court hearing over the sale of Fratton Park, and for the PST to raise the remaining funds as set out in their business plan, before fully considering their application.
PST chairman Ashley Brown said: "We are very pleased the Football League has shown confidence in our bid by endorsing our proposed membership. This is a highly significant moment for the club.
"We have always argued that Pompey needs a community-led solution and we are very pleased the League shares our confidence in our ability to turn the club around.
"Thanks to the backing of our fans and our individual investors we have a robust business plan, which the League has endorsed.
"We now need fans to back us financially to ensure our club survives. This is a landmark moment on the road to rehabilitating the club and we now need everyone who can to buy a share or convert their pledge as soon as possible. This will ensure we are in a strong financial position prior to the court case."
The Trust's bid, and Portsmouth's future, hinges on administrators PKF gaining permission to sell Fratton Park, which is controlled by the club's former owner Balram Chainrai, at the High Court hearing which starts on Thursday.
The League have also confirmed Pompey still face a 10-point penalty if and when they finally come out of administration, which is likely to leave them in the relegation zone.
Brown added: "Of course we are disappointed that the League has confirmed the points deduction, although the reasons for it are the fault of those who have mismanaged the club so badly in its recent past."
