Kilmarnock manager Allan Johnston expects to make a decision on his four trialists next week.
Former Rangers striker Nacho Novo, former Hearts defender Ismael Bouzid and Tunisian Tijani Belaid, who once had a short spell with Hull, have all arrived for a trial with the Scottish Premiership club while winger David Silva is trying to win a return to Rugby Park.
None of them is expected to sign before the visit of league leaders Inverness tomorrow, but Johnston is looking to sign two players to bolster his squad and deals could be done next week.
Johnston, whose team have yet to win a game this season, said: “We’ve got four trialists in. They have been training with us this week.
“We are not going to rush into a decision but hopefully we can make a decision within the next week or so.
“It would be good to bring in a centre-half and an attacking option as well, whether that’s wide or up front, just to add a bit of creativity.”
Bouzid made 65 appearances for Hearts during two seasons at Tynecastle from 2009 to 2011, winning an international recall with Algeria.
The former Kaiserslautern and Galatasaray defender has since had spells in Greece, the United Arab Emirates and his homeland.
Johnston said: “He is a big physical presence at the back and we have just got to wait and see how he goes.”
Novo scored 71 goals in six seasons with Rangers before returning to Spain in 2010. He is looking to win a deal in Scotland and trained with Rangers earlier this year following spells with Sporting Gijon and Huesca.
Silva left Kilmarnock last summer to play for Olhanense in his native Portugal.
