[LNB]"But everyone has to be patient as we can't get too carried away." [LNB]Posh are fifth in the League One table, but remain within reach of the automatic promotion places. [LNB]Mackail-Smith says he shares the fans' excitement at Ferguson's return, and insists a top-two finish has to be their aim. [LNB]"We're in a good position to get promoted, but we'll need time to adjust to playing under Darren Ferguson again," he said.[LNB] [LNB][LNB] Goalkeeper Joe Lewis is continuing between the sticks despite having been placed on the transfer-list by request. [LNB]Mackail-Smith says the rest of the squad are staying focused on the job in hand. [LNB]"Joe has been fantastic throughout the time he's been here and he wants to be playing at the highest level possible," he said. [LNB]"If he has the chance to go and play in the Premier League then that's great, but either way the rest of the lads will get on with it."
