Neil Lennon praised Georgios Samaras after he marked a fine performance with a goal in Celtic's 2-0 Scottish Cup fifth-round win at Inverness.

Anthony Stokes scored twice in last week's 3-1 Scottish Communities League Cup semi-final win over Falkirk at Hampden, but had to settle for a place on the bench on Saturday, with the Greece international one of four changes to the Parkhead side.

Samaras proved an able replacement, firing high past Jonny Tuffey in the 33rd minute to give the holders the interval lead which they never looked like surrendering.

In the 67th minute, after Caley defender David Proctor had conceded a penalty for a foul on Gary Hooper, Parkhead skipper Brown slotted home the spot-kick to seal the win and take the holders into Monday's draw at Hampden.

Asked about bringing Samaras back into the side, the Celtic boss said: "I thought his all-round game was brilliant and I thought he was a real thorn in the side of Inverness, with his height and running power.

"I have been crying out for him to get one of those goals and he really lashed it into the top corner.

"He is capable of doing that so I am very pleased with him today.

"I am delighted to be in the quarter-finals.

"I thought we were fantastic from start to finish and could have been more comfortable.

"The team as a whole were brilliant.

"Their attitude was the most pleasing aspect of the day. Kelvin Wilson came in and I thought he started the game brilliantly, he looked after Gregory Tade very well today.

"And the rest of the team were on the front foot from the first whistle."

Lennon also singled out Brown who notched his third goal in three games to extend Celtic's domestic winning run to 15 games and keep them on course for the treble.

The former Celtic skipper said: "He is just in a good place at the minute. He has been very consistent

"I asked him to lead the team today because we would be asked plenty of questions and he has done fantastically well again.

"We are seeing the best of him now."

Caley never looked like providing a shock and manager Terry Butcher described the defeat as the "worst performance of the season".

He said: "It was like a training match for Celtic today.

"They worked harder than us and that is an awful thing to say.

"I can't believe how frustrating it is and how disappointed I am.

"We just let everybody down.

"Celtic could have scored more goals and the only positive I can take from the game is that we only lost 2-0.

"We hardly had a shot, we hardly had a cross and we hardly had any decent play in their half and the penalty was a comedy of errors."
