The Ibrox boss has arranged a closed-door match with Partick Thistle at Murray Park to have a look at Georgie Welcome, Nacer Barazite and Dutch winger Etienne Esajas.
Former Sheffield Wednesday man Esajas arrived in Glasgow last night, the 25-year-old having been recommended by Gers fitness coach Adam Owen, who worked with him at Hillsborough.
Esajas has already had trials with Charlton and Turkish side Konyaspor this summer, but did not win a contract.
Smith will also closely watch Arsenal kid Barazite after the Dutch Under-21 star impressed during a pre- season friendly with Glen-toran in Belfast last week.
Welcome has been in Scotland for a fortnight and has been improving his fitness – but Smith wants to see him in action before making a decision on the Honduran.
Smith said: “One of the main reasons we are holding this game is to look at Nacer, Georgie and some of our younger boys who have not had many games.
“It has been a bit unfair on Georgie, in particular, because he has not had the chance to play yet. You can see certain things in training, but you cannot make a decision until you see a player in a game.”
But landing top target Nikica Jelavic isn’t proving easy as chief executive Martin Bain revealed Rapid Vienna have moved the goalposts again.
Rangers have already agreed personal terms with the Croatian striker and settled on a £4mfee with the Austrian club.
But Rapid say they want him to stay until after the Europa League play-off matches against Aston Villa this Thursday and next week.
Jelavic was set to hold showdown talks with his club today and tell them he wants to be sold immediately to Rangers.
Bain said: “Rapid have moved the goalposts and this is not acceptable. We expect the player to be in Glasgow in the next 24 hours for a medical.”
There have been conflicting reports on Jelavic’s eligibilty for Rangers in the Champions League should he sign, given that he’s played in two Europa League qualifying rounds for Rapid.
A Uefa spokesman clarified the situation today, stating: “If a player represents a club in any of the qualifying rounds of the Europa League, and they then go through to the group stages, he would be ineligible to play for a new club in the Champions League.
“If his former club are knocked out in the qualifying rounds, he can play in the Champions League for a new team if registered before September 1.”
There are also difficulties in landing Tommy Smith from Portsmouth despite a £1.5m fee being agreed last week.
The transfer embargo placed on Pompey has left them struggling to replace anyone sold on.
Pompey gaffer Stever Cotterill said: “Tommy isn’t for sale.
“If he happens to go anywhere like Rangers today, I don’t know anything about it.”
