With Christian Ziege having been absent pretty much since Boxing Day - although on target for a reserve team outing on Monday - the manager felt that he needed another 'leftie' in his squad.
After the transfer of Bobby Convey fell at the final hurdle, the opportunity of signing England under-21 international Konchesky was not one to be resisted.
"It was a late one, we'd had conversations before about possible swap-loans with other players that didn't materialise," revealed Glenn.
"We've had Christian out and I felt we needed a left footer - we tried to bring Bobby Convey in and that fell down at the last moment.
"Charlton came onto us about Chris Perry and it is a juggling act sometimes. They said Paul could come this way so we could have a look at him for a month or two, so it suited them and us."
Glenn added that he has been more than pleased with the contribution of Mauricio Taricco in the left wing-back slot and points out that Konchesky is a player that can perform in a number of roles.
"It's nice to have a left sided player in the squad for when we feel we need that natural ability on the flank. Tano is doing a great job out there and we've been looking at and working with young Dean Marney on the right and left.
"I just felt that it was a strength we needed perhaps and it adds to the squad.
"Paul has got good talent and can play at left full-back, wing back or left midfield - I've even seen him play on the left of three at the back. So he can play in a number of positions when called upon which is good for us."
Glenn Hoddle says the recruitment of Paul Konchesky on loan gives his the option of deploying natural left-sided ability.
