Celtic are continuing talks with West Ham United star Albian Ajeti.
The attacker was set to join the Scottish giants after the two teams agreed on terms for a loan with an option to buy agreement.
Sky Sports says the player is not sure about whether to make the move as he wanted more time to consider his options.
Celtic boss Neil Lennon is having talks with Ajeti and his representatives about the move.
The player wanted a Premier League stay, but Celtic can offer European football, and the chance of regular football.
The 23-year-old also has interest from West Bromwich Albion, who are newly promoted to the top flight, to consider.
