Linfield are tracking Glentoran duo Conor Pepper and Navid Nasseri as David Healy aims to boost his squad ahead of Champions League participation next month.
The Blues will play San Marino kingpins Tre Fiori behind closed doors on August 8 in a Euro schedule that has been revamped due to Covid-19 and Healy is determined to bring new faces to the club.
The transfer window opens on August 1 and the recently crowned Champions want to unveil three or four new players next weekend.
Chris Johns is one, having signed a pre-contract deal to join Linfield when the current season ends on Friday night.
The Blues are in the market for a right-back and creative midfielder following the departure of Chris Casement and Joel Cooper - and Pepper and Nasseri are firmly in their sights.
Both players are out of contract at the end of this week and it is understood Pepper will likely leave for Windsor, while Nasseri is keen to play European football, which Linfield can guarantee, with the Glens needing to win the Irish Cup to qualify for the Europa League.
"We are confident Navid will be with us," said Glentoran boss Mick McDermott this week. "He likes being here and, as the days go by, is realising this is the place for him."
Blues sources are hopeful Nasseri will join them but insist they have other irons in the fire should the 23-year-old stay at The Oval.
Linfield starlet Charlie Allen will, meanwhile, officially join newly-promoted Leeds United in a six-figure deal reported to be worth £300,000.
The 16-year-old forward was also attracting interest from Rangers and Chelsea, but will make the move to Elland Road.
