Neil Lennon has revealed that Celtic are on the brink of signing Israeli midfielder Nir Biton and Finnish striker Teemu Pukki.
Biton is set to join Celtic from FC Ashdod, with Lennon confident that he would be a good addition to the ranks at Parkhead.
Lennon has declared that the signing of Biton is "more or less in the bag."
He added: "He will come into the squad so that will freshen us up."
The Northern Irishman also stated that Celtic "were close" to clinching the signature of Pukki.
Lennon claimed on Wednesday night that he had agreed a fee with Schalke for the striker, but not personal terms.
Both would be available for the Champions League campaign, and winger James Forrest believes the 2-1 victory over Barcelona last season will give Celtic confidence in their six big European nights.
He said: "It obviously gives us a bit of confidence knowing we can do it against big teams but we know it will be tough
"It could have been easier. Three big teams and we know it's going to be difficult.
"It is definitely a tough group and Barcelona and Milan will be the favourites."
