With the impending departure of Nigel Winterburn at the end of the season, Glenn insists there is still plenty of quality, and quantity, in the left back position.
"We have still got Scott Minto, who has another year on his contract," he says, "and, unless anything changes in the close season, we'd have to take the view that Scott will be looking to understudy Vladimir Labant to start with - and who knows whether he will play more games next year."
Scott has started six times this season and returned to action for the reserves on Tuesday, and Glenn adds: "He has come in a few times this year and he hasn't let anyone down, and while he has got a contract at the club he will obviously figure in our plans for next year."
As for Nigel coming near to the conclusion of his West Ham career, Glenn says: "If any manager calls me I will give him the highest recommendation. I can't say enough good things about Nigel, but everything, in the end, has to come to an end."
Glenn says there will be no let up in the final four matches, and insists: "We want to finish with a flourish and pick up as many points as we can in the remaining difficult games.
"Sunderland still need something when they come to us, which will make the game that much more difficult.
"And we end the season with a home game against Bolton, hoping to finish with a win, because we'd like to send our fans home happy at the end of this season."
