JASON Denayer today vowed to help shore up Celtic's porous defence in the second leg of the Europa League showdown with Italian cracks Inter Milan.

Denayer jetted out of Glasgow for Milan along with the rest of the Hoops squad this morning ahead of the last 32 tie in the San Siro tomorrow night.

The fixture is delicately balanced at 3-3 after an explosive meeting between the two teams in front of 60,000 fans at Parkhead last Thursday night.

Ronny Deila's side looked suspect at the back at times during that thrilling encounter - as they have often done in Europe during the 2014/15 campaign.

Indeed, the Scottish champions have now conceded 22 goals in their Champions League and Europa League outings this term.

However, Belgian centre-half Denayer is confident Celtic can progress to the next round of the continental competition with an historic triumph.

The 19-year-old defender, though, knows that his side has to perform far better at the back against Robert Mancini's expensively-assembled team to go through.

He said: "I was happy about how we played in the Milan game last week. Unfortunately, we started poorly and made a few mistakes as a team and that, ultimately, cost us victory.

"The intensity of the game was very great to begin with and we struggled. But we challenged that and did well after that.

"We played very well in the second half and created a lot of chances. I think that gives us confidence going to Milan. I think we can do it over there."

Denayer added: "Inter were exactly what I expected them to be; a very talented team with a lot of very dangerous players.

"It is going to be a very difficult game because they are a good team and they are playing in front of their own supporters in their own stadium.

"It will be a different game over in Italy to the one we played in Glasgow last week when we had an amazing support, 60,000 fans, behind us.

"The support helped us a lot last week. They put a lot of pressure on Inter Milan and helped us to keep going and get back into the game after going 2-0 down.

"It was a great atmosphere. The supporters were amazing. It was difficult at the start. But we played very well after that and in the second half especially.

"Over there the crowd will be more behind Inter. But I am looking forward to playing at the San Siro Stadium. It is one of the biggest and most famous stadiums in Europe.

"It will be an amazing experience. This will be the first time that I have played in Italy and I am looking forward to it. Everybody looks forward to this game.

"But we know we can't give away as many chances at the back as we did last week and expect to win the game and go through. But we are determined to do that and believe we can do it."

Denayer, who is expected to be fit despite suffering cramp in a calf in the 4-0 win over Hamilton Accies on Sunday, has gained great experience playing away from home in Europe with Celtic this season.

The Manchester City loan star has played against NK Maribor, Salzburg and Astra Giurgiu away - and hasn't suffered a defeat in any of those outings.

He said: "I know what is expected when we go away from home in Europe. There is definitely a different edge to the game when you play away.

"But this is still a game that we can win. We have shown this season that we know how to play away from home in Europe and do well."

Stuart Armstrong and Gary Mackay-Steven both made their European debuts for Celtic in the game against Inter Milan last week.

Armstrong and Mackay-Steven had previously played for Dundee United in the qualifying rounds of the Europa League against Dinamo Moscow two seasons ago.

But the central midfielder and the winger made a massive contribution in the meeting with the Serie A club and impressed hugely given their lack of experience in European competition.

Armstrong especially. He netted his side's first goal and then pressurised Hugo Campagnaro into turning the ball into his own net shortly after that.

Denayer is positive the new Bhoys, who joined Celtic from United during the January transfer window, will be able to handle the enormity of the occasion if they are selected by manager Deila.

He said: "Stuart and Gary have both integrated well into the team since joining us last month. They both have great confidence in themselves as players.

"I am happy for them both and I am sure that they will handle the game brilliantly if they are picked to play in this match.

"But whoever is selected by the manager to take part in this match will do well. We have a lot of quality players in the squad and great competition for places as well.

"This will not be an easy game. We all know just how hard it will be for us. But we're confident that, if we don't give away goals so easily and take our chances when we get them, we can win and go through."
