The boss has gone on record recently emphasising the need to reinforce the central defensive area, along with a back-up goalkeeper to replace Ian Walker.
"I will make two additions to the team before the start of the season, a goalkeeper and a central defender," said Glenn"
Glenn was not greatly distressed over the team losing and unbeaten tag earned over eight previous warm-up games, stressing that the preparation games are all about being ready to face Aston Villa on Saturday.
"It is disappointing to lose a match but we had three games in a week and we felt physically weak," reflected Glenn. "We want to be ready for the beginning of the Premiership.
"This is the first match we have lost this pre-season and the goal of the club is to improve on last year's finish."
Glenn has confirmed that he is closing in on two more new recruits after witnessing his reshaped side fall to a first defeat of pre-season against AEK Athens.
