Glasgow club, Celtic have sent clear warning signs to FC Barcelona ahead of the champions league knock-out clash.
The Scottish club remained firm at the top of the Scottish league with another convincing performance, hitting three past Gretna and hitting another three on the opponents woodwork before the match ended. Celtic were clearly in control of the match from start to finish, giving the likes of McDonald, McGeady and Brown the opportunity to showcase fine skills, each scoring on the night. FC Barcelona will need to be extra careful against the rampaging Scots when both sides meet in the champions league second stage in a winner takes all, two-legged face-off.
