It's the 反逆者／反逆するs vs the 設立! Upstarts Union Berlin 長，率いる to 10-in-a-列／漕ぐ／騒動 支持する／優勝者s Bayern Munich with only goal difference splitting them in thrilling Bundesliga 肩書を与える race... so can they pull off a Leicester-style 奇蹟?

• e-mail

Union Berlin has always had a 反抗的な streak. In 共産主義者 East Germany, they never really stood much chance of success when 競争相手s BFC Dynamo had the 支援 of the Stasi.

On the 崩壊するing terraces of their Stadion An der Alten Forsterei, 反体制者s of the 政権 felt the safety in numbers to shout things they would never dare on the streets.

'負かす／撃墜する with the 塀で囲む!' was reputedly such a 詠唱する when Union won a 解放する／自由な-kick and the 対立 始める，決める up to defend it. Part of the Berlin frontline during the 冷淡な War was in football stadiums.

Now Union are taking on another form of 設立. Bayern Munich have won Germany's Bundesliga in each of the past 10 seasons, often in little more than a stupefyingly dull 行列.

But not this time. 21 matches into the （選挙などの）運動をする and remarkably, three teams are locked together on 43 points at the 最高の，を越す of the （米）棚上げする／（英）提議する entering this 週末.

Union Berlin are giving the Bundesliga 設立 a serious run for their money this season

It's been a remarkable season for Union, who also （警官の）巡回区域，受持ち区域 Ajax in the Europa League this week

It comes as no surprise that Bayern are one of the trio. It will raise few eyebrows to see Borussia Dortmund are another. But then there's Union Berlin - 井戸／弁護士席, they're not supposed to be there.

This Sunday, upstarts Union make the trip from the 資本／首都 to the Allianz 円形競技場 to take on Bayern in a match that will go a long way to deciding the 結果 of the 肩書を与える race.

For the first time in a long while, Bayern look 動揺させるd and their 競争相手s are ready to pounce. They have won just two of six league matches since Germany's 最高の，を越す-flight 再開するd after the World Cup and winter breaks.

割れ目s are beginning to show in their usually flawless facade. There has been the 列／漕ぐ／騒動 伴う／関わるing Manuel Neuer, who broke his 脚 skiing after Germany's World Cup 出口 and was then enraged by Bayern's 解雇／（訴訟の）却下 of goalkeeping coach and の近くに friend Toni Tapalovic.

The club 申し立てられた／疑わしい Tapalovic had been 漏れるing （警察などへの）密告，告訴（状） from the coaching staff, something club captain Neuer 反駁するd before その上の 増大するing 事柄s by （人命などを）奪う，主張するing it felt 'like his heart was 存在 ripped out.'

Then there's coach Julian Nagelsmann, who was left 激怒（する）ing at 審判（をする） Tobias Welz after defender Dayot Upamecano was sent off just eight minutes into their 3-2 敗北・負かす at Monchengladbach last 週末.

Nagelsmann ranted at Welz for his 業績／成果 and made a point of going into the 審判（をする）'s room 地位，任命する-match in 十分な 見解（をとる） of 新聞記者／雑誌記者s.

Things have not been running 滑らかに for Bayern Munich, who are usually 井戸／弁護士席 （疑いを）晴らす by now

Julian Nagelsmann was livid at 審判（をする） Tobias Welz as Bayern lost 3-2 at Monchengladbach?

Dayot Upamecano was sent off by Welz just eight minutes into Bayern's loss last 週末

He apologised on Twitter afterwards, 説: 'Emotions are part of sport. And given the red card, I had to vent after the game.

'However, I have to apologise for the choice of words to the team around Tobias Welz. Unfortunately I went too far there.'

Every Bayern coach is 絶えず under 圧力 but if Nagelsmann thought the 支持する／優勝者s League 勝利，勝つ over Paris Saint-Germain had 緩和するd 緊張s, he was mistaken.

The 統治するing 支持する／優勝者s have won just 12 of their 21 league games so far, their lowest at this point since 2010-11, when Jurgen Klopp's Dortmund won the 肩書を与える and Bayern finished third.

So the 適切な時期 is very much there for someone else to capitalise and break Bayern's long run of 選手権s.

When Union topped the Bundesliga in the 開始 weeks of the season - the first time they'd led a 最高の，を越す 分割 since 1970 in the DDR-Oberliga - everyone assumed they'd quickly 宙返り／暴落する 負かす／撃墜する again.

German football's 反逆者／反逆する club are living the dream 権利 now as they 押し進める at the 最高の，を越す of the （米）棚上げする／（英）提議する

But even though coach Urs Fischer kept 主張するing the team's No 1 客観的な was to 避ける relegation, they kept 証明するing incredibly difficult to （警官の）巡回区域，受持ち区域.

With only one of their players 長，率いるing to Qatar for the World Cup, they remained 比較して fresh compared to their 競争相手s and duly won five 連続した league games after the 再開する.

Indeed, it was 見解（をとる）d as a major let-負かす／撃墜する when they dro pped two points in a goalless draw at home to struggling Schalke last 週末.

But Thursday night's brilliant 3-1 勝利，勝つ over Ajax to 始める，決める up a Europa League last-16 date with ベルギーs Union Saint-Gilloise 単に continued the fairytale nature of their （選挙などの）運動をする.

For the 記録，記録的な／記録する, they're also still in the German Cup, travelling to Eintracht Frankfurt in the ４半期/4分の1-決勝戦 in April.

If Leicester City taught us anything in 2016, it's that 奇蹟s can happen in football and the whispers are growing louder.

Leicester famously won the 首相 League 肩書を与える in 2015-16 at 半端物s of some 5000-1

Dortmund cannot be counted out of the Bundesliga 肩書を与える race as they take on Bayern and Union

Union have remarkable 力／強力にするs of 回復, 救助（する）ing 12 points from losing positions this season - more than any other team in Europe's 最高の，を越す five leagues.

Their game 計画（する） is based on 激しく揺する solid 防御の 創立／基礎s and their 24 goals 譲歩するd in the league so far is second only to the 21 let in by Bayern.

If they can 追加する to Bayern's problems and 現れる from Sunday's game with a point or a 勝利，勝つ, it will only 追加する to the 疑惑 they aren't going to 落ちる away during the run-in.

Dortmund, who travel to Hoffenheim on Saturday afternoon, are also 井戸／弁護士席-placed to pounce on any Bayern slip-ups.

They have won all six games since the winter break, の近くにing what was a nine-point gap. Julian Brandt has been in sparkling form, 伴う／関わるd in five goals in those half-dozen games, while Karim Adeyemi has netted in his last four.

Unfortunately, the striker has 苦しむd a hamstring 傷害 and will be sidelined for a while.

For a change, the Bundesliga looks 始める，決める to 配達する an engrossing and 予測できない 肩書を与える race. While やめる a few in Germany just want some one else other than Bayern to 勝利，勝つ it, you 嫌疑者，容疑者／疑う 反逆者／反逆する club Union would be the true people's 支持する／優勝者s.
