Peterborough United manager Mark Cooper has said he expects to complete permanent deals for all of the club's current loan players.Ryan Bennett, Scott Griffiths, Josh Simpson and Exodus Geohaghon are all on loan with a view to permanent moves. [LNB]Cooper told BBC Radio Cambridgeshire: "All the deals are agreed and will happen, it's just a matter of who we add to that bunch. [LNB]"We're looking for four or five players and in a variety of positions." [LNB]Cooper says Posh must strengthen in all areas if they are to survive in the Championship. [LNB]He saw his side fight back from four goals down to earn a 4-4 draw at home to Cardiff on Monday, but knows changes must be made. [LNB] [LNB][LNB] "We failed to do the simple things like wanting to tackle and wanting to compete, " he said. [LNB]"If you can't do that you won't win any games, be it on a Sunday morning or against Cardiff in the Championship." [LNB]Posh battled back into the Cardiff game using a five-man midfield, with substitute Josh Simpson scoring twice. [LNB]However, Cooper says the quality of players at his disposal, rather than which system they play, will dictate whether or not they beat the drop. [LNB]"It doesn't matter what system you play, you need people who want to wear the shirt and play for Peterborough United," he said. [LNB]"We must become more solid and if playing 4-5-1 is what it takes then that's what it takes, but ultimately it's all about the personnel." [LNB]Posh take on Tottenham in the third round of the FA Cup on Saturday with defender Gabby Zakuani having suffered a reoccurrence of a thigh strain. [LNB]Fellow defender Ryan Bennett and goalkeeper Joe Lewis should play having shaken off knocks, but Josh Simpson and Exodus Geohaghon are cup tied. [LNB]Aaron Mclean is struggling with a virus and may have to settle for a place on the bench having been taken off at half-time in the Cardiff match on Monday. [LNB]Left-back Tommy Williams is in contention for a place after his loan spell at QPR came to an end.
