Along with bolstering the defence, Neil Lennon must devote serious attention in adding depth and quality to his attacking department.
The Celtic boss will be heavily relying on Leigh Griffiths this season but no one knows how the 28-year-old will fare after he was given lengthy time off by the club to sort out his personal problems.
There is Odsonne Edouard who has done well in patches. Although he has tremendous potential, Lennon cannot afford to build a team around him just yet.
Vakoun Issouf Bayo is another option, but Lennon must sign someone who is experienced and goals are guaranteed from him.
