Storm Frank threw a spanner into Glasgow Warriors' plans to avenge their defeat to Edinburgh last week, as their Scotstoun home - which was sold-out = was ruled unplayable just 48 hours before kick off.

After a frantic day of logistical planning, the Warriors confirmed that they would controversially return to Murrayfield to play the deciding leg of the 1872 Cup with a reduced capacity, mainly of Warriors fans.

The announcement was met with widespread anger by Warriors fans who were unable or unwilling to make a second trip along the M8 for what was supposed to be a home fixture, but the match went ahead as scheduled.

Glasgow Warriors 11-14 Edinburgh (22-37 on aggregate)

It was a case of same teams, same venue, same result on Saturday evening as the Warriors suffered their first back-to-back 1872 Cup defeat since the format began seven years ago, at the hands of a magnificent defensive effort from their rivals.

Gregor Townsend had asked jaded Warriors supporters to turn Murrayfield blue yet again and get behind their team as best they could, but even the use of the home dressing room and reduced capacity of the national stadium couldn't inspire his side to reclaim the old trophy.

Capital defence

Once again Edinburgh's defence was outstanding. They made nearly 150 tackles in total, and despite being breached once again by Glasgow centre Mark Bennett they held firm at the end - even after an incredible 22 phases camped on their own try line.

They held off their rivals for the second week in a row and retained the 1872 Cup and four valuable Pro 12 points in the process, adding to the four they collected last weekend, which sees them now sit fourth in the table.

Warriors woes

For Townsend, however, there is much to ponder ahead of a crucial three week period of back-to-back European Champions cup fixtures. There is now the real possibility of a winless month for the first time in almost five years.

Despite a strong start to the contest, every time the Warriors edged over the gain-line a mistake swiftly followed. Re-called number eight Josh Strauss, captain Jonny Gray and flanker Ryan Wilson all brought the necessary physicality that was missing in the first leg. But more often than not, slow ball or handling errors put paid to any try-scoring opportunity.

Second half slump

Despite the stage being set for an exciting finale to the two-legged clash, the second half was one to forget for both sides. But after yet another penalty for the 'visitors' was kicked to the corner instead of the posts, Edinburgh stand off Phil Burleigh managed to evade Stuart Hogg's tackle before his momentum took him over the line for the winning try.

Lineout woes

Both sides will also be concerned with just how much of a farce the lineout became throughout the match. Both starting hookers Fraser Brown and Ross Ford frequently missing their targets which will be of major concern for national forwards coach Nathan Hines who was an onlooker at Murrayfield, knowing that the visit of England in the Six Nations is now less than five weeks away.

Their replacements Shalva Mamukashvili and Neil Cochrane respectively, didn't fair much better in the latter stages. However, Glasgow's driving maul was an effective weapon which was only deployed when the lineout ball was secure, which was seldom to say the least.

Townsend praise

The Glasgow head coach was typically optimistic in the aftermath saying: "I have to praise my players' efforts to get back from three points behind to almost get the win, but it wasn't to be today."

"Fair play to Edinburgh though," he continued. "That's two weeks in a row they've taken their opportunities and that's a sign of a confident team."

Solomons joy

Edinburgh boss Alan Solomons on the other hand, now believes that his side has now closed what was once a significant gap between the two Scottish rivals.

"The players there in the last two minutes were just incredible - they weren't going to lose that game, that's for sure," he told BBC Scotland. "I've felt that over the last couple of seasons, we've definitely closed that gap (between the two sides)," he continued as his players celebrated three wins in a row against the Warriors.

Continuing controversy

Despite Edinburgh effectively ending their away hoodoo against the Warriors, much will be made of the fact that this match went ahead at all.

One can only speculate what the outcome would've been had the match been played at a sodden Scotstoun, but you would have thought the Warriors would've found a way over the try line at the end of the match with a capacity crowd behind them. It was not to be, though.

Credit must go to Edinburgh, however, as their outstanding defence held out yet again to re-ignite their domestic season and a top four place must now be the minimum target for the season.

Warriors worries

At the other end of the M8, however, the reigning Pro 12 champions look a shadow of the team that was so exciting to watch last term, and they now languish eighth in the table, albeit with two games in hand.

There is no doubt that a combination of World Cup involvement, postponements and injuries have taken their toll on Townsend's squad, but they really need to rediscover their spark quickly as the next three weeks will be a real test of their mettle against Europe's best.

Pro 12 Wrap

The second round of regional derbies continued this weekend in the Guinness Pro 12 as last season's finalists Munster finally ended their losing run with a hard-fought 7-9 win away to rivals Ulster on Saturday.

Meanwhile Leinster won their second match in six days as they defeated inter-provincial rivals Connacht 13-0 at a wet and windy RDS in Dublin on New Year's Day.

In Wales there was another tasty derby match at the Arms park as Cardiff Blues snatched an unlikely 29-27 win over top side Scarlets thanks to a late Alex Cuthbert try. Whilst in Swansea, the Ospreys held off a late comeback from regional rivals Newport Gwent Dragons in a 12-7 home win.

In the "derby d'Italia" Zebre did the double over their fierce rivals Treviso at Stadio Monigo in a 8-18 away win to register three back to back wins for the first time in their history.
