Brendan Rodgers says Celtic needs more investment to compete in Europe

They have an upcoming fixture at Monchengladbach on Nov. 1 before hosting Barcelona and end their group campaign at Manchester City.

“There are certain attributes you need and of course that does cost you money,” Rodgers told British media. “That will be up to the club and our recruitment to look and try to find these players.

“We know that availability and affordability figures, but it is something that will happen over a period of time… No matter how good we might be there are still elements we need to compete consistently at this level.

“We are in the process of building something; it was brilliant to qualify and we are giving everything, but sometimes there are teams which are better than us. That’s no disrespect to my players.”
