After a three day trial, Dmitry Verkhovtsov has accused Celtic of wasting his time. The 23 year old spent time last week with the Hoops before returning to Naftan Novopolotsk.
He said: "I honestly still do not quite understand what happened.
"I went to Scotland but didn't do any medicals nor participate in training sessions.
"Throughout the three days, all I had to do was wait until they bought me a ticket to return home. I was given no explanations by any of their managers.
"Naturally, I would like to test myself playing for such a famous team."
Celtic refuted the player's claims, saying he was treated with "the utmost respect".
Despite the experience, Verkhovtsov's agent hopes a move could be resurrected at the end of the season.
Valeri Isayev said in the Scottish Sun: "Initially, we talked not about a full-scale contract but a half-year loan.
"Celtic let us know their conditions, but when we arrived in Glasgow those were changed.
"As a result, we failed to reach agreement. I don't want to go into more details about it now.
"As for Verkhovtsov's transfer value, it was not even discussed.
"We are going to return to the issue in summer."
