Griffiths insists Celtic must be wary of Morton threat

Leigh Griffiths insists Celtic need to be wary of lightning striking twice after the Premiership leaders were drawn at home to Greenock Morton in the quarter-finals of the William Hill Scottish Cup.

The draw at Hampden Park, which had to be re-run after one of the plastic balls opened after the Hoops had been paired with Dundee United at Tannadice, saw the Championship side set for a return to Parkhead, the scene of a famous and unlikely League Cup win in September, 2013.

Dougie Imrie's penalty in extra-time shocked the home side and Griffiths believes the current Celtic team need to be on their guard.

The 29-goal striker said: "The last time they played us at Parkhead they beat us so we need to be wary of that.

"The players like Scott Brown, Charlie Mulgrew, James Forrest, who were involved in that squad just before I signed will be telling everybody else that regardless of the opposition we need to take care of them professionally."

Morton midfielder Joe McKee, who was injured when Ton beat Celtic, is looking forward to playing a full part this time.

He said: "I had an ankle injury at the time and was in the stand watching, but the boys were magnificent that night and they pulled off a shock so these things happen.

"You see cup shocks happening now and again so you never know.

"I was down in the changing room with all the boys and the atmosphere was unbelievable.

"Obviously mixed emotions for me that night, not to be playing but it was a great atmosphere and I was happy for all the boys.

"We will go and try to give a good account of ourselves and see what happens."

Holders Inverness were handed a tough tie with a trip to either Hibernian or Hearts who will play again at Easter Road after a 2-2 draw at Tynecastle.

The winners of the Rangers and Kilmarnock replay at Rugby Park will take on Dundee or Dumbarton, who have to play again after a goalless draw, while Ross County host Dundee United with the ties to be played over weekend of March 5 and 6.

Hearts defender Jordan McGhee is looking no further than the replay against Edinburgh rivals Hibs.

He said: "It is a good draw, a tough draw but it doesn't make it easier that we have an Edinburgh derby to play again next Tuesday so we look forward to gettting that out of the way first.

"Obviously it is dificult with them (Hibs) at home but I felt we played well enough in the first-half and if we play like during the full game and don't come off the tempo in the second half we will have a right good chance.

"But we just need to work on the other things that we didn't do well and improve on them."

Hibs midfielder John McGinn insists the Championship side are not taking anything for granted just because they will face the Gorgie men at home.

He said: "We had to get that balance yesterday, we didn't want to over celebrate because we haven't done anything yet, we only managed to secure another game against Hearts.

"We know we need to be cautious and there is still a lot to do to get through.

"We just have to focus on the replay next week and if we manage to get through that then the next round is a tough one.

"We are at home and we fancy ourselves against anyone at home but it is going to be a tough game, a derby and anything can happen. When we play at our best we don't fear anyone."

John Brown, who played for Rangers' nine-in-row side which spanned the late 1980s and 1990s, admits Mark Warburton's Championship leaders would appreciate a run to the cup final, but believes promotion back to the Premiership should be the focus.

He said: "I would prioritise winning the Championship. If you get a run in the cup then great.

"My last game for Rangers was the Hearts cup final 20 years ago this May and we won 5-1 and you carry those memories for every more.

"For these Rangers players to get the opportunity to set up a home tie with a view to a semi-final, very close to a final, they have to take it, it doesn't come round that often.

"Looking at the Rangers side of things, if we can get through against Kilmarnock it is a home tie against one of two decent teams.

"I have seen Dumbarton and Dundee so it wouldn't be an easy tie, but it is a home tie that Rangers would expect to win to set up a semi-final.

"It is a great carrot for the next game against Kilmarnock and if they get through that I am sure Ibrox would be full.

"But going up has got to be the priority. We missed out last year, that was a sore one and the fans are desperate to get there.

"I think Mark Warburton has been excellent, he has brought in virtually a new team and to be in the position we are in the Championship and pushing to win the league, I think that is a priority."
