THE closest thing to a spying mission Neil Lennon has undertaken in the lead-up to the Champions League rematch with Barcelona was a family excursion to the cinema to see the James Bond film Skyfall.

The Celtic manager gathered his squad in front of the television at the team hotel last night to watch the Catalan giants take on Celta Vigo, but he is well aware that, whether it is home or away, domestically or abroad, Barca line up almost exactly the same way and attempt to impose themselves on their opponents in exactly the same formidable manner. Lennon was keen that Wednesday night's match at Parkhead shouldn't distract from what could be a tough SPL encounter with Dundee United today, but his players would hardly be human if thoughts weren't wandering ahead to their European assignment.

Understandably, Lennon will not throw caution to the wind as his side attempt to better their last-gasp 2-1 defeat in the Camp Nou just under a fortnight ago, but he would love his team to see more of the ball – they had only 26% of the possession last time – and hopes to open up more "avenues of attack".

Lennon said: "The fans will have to be patient, but I think they are pretty well versed in the fact Barcelona dominate possession home or away. I will try to watch some footage of games they've lost and see if I can pick up on anything.

"But in the main I'm going to concentrate on what we're going to do. It's a different sort of mentality going into this game because we're at home. We will be more adventurous, but we definitely won't be gung-ho about things."

Some good news for Lennon is that central defensive pair Gerard Pique and Carlos Puyol are still injured and Sergio Busquets serves the second game of his suspension.

Lennon said: "They may go with [Marc] Bartra and [Javier] Mascherano again so it will be interesting to see how they line up in the weekend game. I think they will be wary of us at set-pieces and they should be. If we get our delivery right we can be a real threat. But we are not pinning all our hopes set-pieces. I want us to try to have more of the ball in open play and be more of an attacking presence."

Emilio Izaguirre's display in the Camp Nou was particularly heartening for Lennon, considering the Honduran has been criticised for his defensive work and suffered a difficult Champions League baptism in the home match against Benfica.

"I was really pleased with Izaguirre's performance in terms of his defending," Lennon said. "It's an accusation that's often laid against him, that his defending is not the greatest. He really proved at the Nou Camp that when he puts his mind to it, he can put everything together."

No-one was more pleased with the way he played than Izaguirre. He said: "The Benfica match was a very hard game for me because it came on the back of a very long journey from international duty and two games against Cuba.

"It annoyed me that I wasn't going into the game 100% and it was my first experience of the Champions League so it was tough. It was a build-up of things and it was hard but I've come a long way since then."

Izaguirre played against many of Barcelona's stars for Honduras against Spain at the 2010 World Cup and watched on television as his country beat the Spanish in Newcastle at the Olympics.

"I wasn't able to play because of the Champions League but watched it on TV," he said. "It shows that if you have the mentality to go out hungry for a win, it can happen."

The major lesson Barca taught Celtic in the first match was the importance of playing to the final whistle, with the Parkhead men conceding seconds before the end of each half. Lennon said: "They have a fierce will to win, but it also helps when you can bring on David Villa with 10 minutes to go."
