Celtic's Champions League visit to Barcelona may require the Catalan club to open its mini-stadium and show the knockout match on a giant screen for fans without tickets, according to the city council.

And Scottish fans who make the trip in March will face strict controls and possible fines if they try to congregate and drink alcohol in public places.

Civic leaders were deluged with complaints from Barcelona citizens during and after Rangers's Group E game in the city last month and the "softly-softly" approach adopted by local police came in for bitter criticism.

The fact that so many fans without tickets arrived in the city for an extended stay, that four tonnes of rubbish was cleared from Plaza Cataluna and that "uncivic" behaviour - including vomiting, scuffles and public urination - was commonplace, has caused the council to announce a clampdown on public consumption of alcohol.

More than 150 Stuttgart fans were fined for drinking in public before and after Barcelona's final group game. In comparison, the Rangers fans were left alone to drink carry-outs around the city centre.

The new, tighter laws will apply when Celtic fans arrive in March and the council leader in charge of public order has revealed that city bosses have demanded FC Barcelona, Uefa and the British Council help them in clamping down on uncivic behaviour from visiting fans.

"The Rangers game caused this city public order problems. That will always be the case when a Champions League match brings a club with thousands of followers who arrive without tickets and drink massive quantities of beer," said senior councillor Assumpta Escarp.

"We've spoken directly with Uefa, FC Barcelona and the British Council about this problem and asked them to try to agree on a common site where fans without tickets can watch the match."

Barcelona FC has yet to comment on its willingness to open its Mini Estadi, where Barca B plays its league matches and which has a seated capacity of 18,000, and erect a giant screen on which to show the Champions League last 16 match which will determine whether the Catalans or Celtic reach the quarter-finals of the tournament.

However one thing is clear, civic leaders will no longer tolerate public drunkenness or even excessive drinking in public - something governed by local bylaws but which was set aside when Rangers took an estimated 20,000 fans to the city in November.

Council member Alberto Fernandez Diaz said: "Local police showed excessive permissiveness when Barcelona played Glasgow Rangers and failed to apply the law on public drinking of alcohol because they thought it was an exceptional' circumstance but we cannot permit a repeat of that."
