Former Celtic star Charlie Nicholas reckons the Hoops were lucky beat Lazio in their last Europa League outing - and has tipped the Serie A giants for revenge tomorrow.

Celts managed a late winner against Lazio at Parkhead a fortnight ago thanks to Christopher Jullien.

The 2-1 win on the night for the hosts made sure they maintained their unbeaten start to Group E and kept them above their challengers.

Despite predicting the correct scoreline, Nicholas believes Neil Lennon's men were lucky to pick up three points.

And he says it'll be a different beast in Rome.

He told Sky Sports: "I'm feeling a bit awkward about this one. 

"Celtic did brilliantly to beat them with a last-gasp winner first time around. I did flag up a 2-1 win, but they were fortunate. Celtic needed to take a good scalp eventually.

"In this one, do they attack, counter-attack or sit in? They are not a team that naturally sit in.

"Domestically, they have 70 per cent of the ball. Celtic are getting better at it and Neil Lennon is asking them to play the ball forward much quicker.

"Lazio will be angry and agitated as they should have gone two or three up at Celtic Park. 

"The Serie A side must win here to stay in the group. Cluj will win I think so it may come down to head-to-head with these two sides. Lazio went fourth in Serie A and will get their revenge in this one."

Prediction: Lazio 1-0 Celtic

Meanwhile Nicholas believes Rangers will earn a more favourable result in their reverse against FC Porto at Ibrox.

Gers did well to gain a point in a 1-1 draw in Portugal and Nicholas has backed them to do so again.

He added: "Like Celtic, the Rangers draw in Porto was something I didn't quite anticipate. 

"Steven Gerrard left out Joe Aribo and Sheyi Ojo, who haven't played at this level before. He went with a cunning and experienced plan and it worked a treat with Rangers playing really well.

"Everyone was expecting them to go back to forward and fill in when they didn't have the ball, but they were worthy of a point, and if not all three.

"Porto are not what they were four or five year ago but are still incredibly dangerous. They are all technically very good players. 

"The passion, drive and commitment can get you over the line, but it will be a frustrating night for Rangers. It is hard to pin who wins this group and this result will leave it wide open with a draw."

Prediction: Rangers 1-1 Porto
