drop zone
Arsenal look to have eased fears of relegation after putting together back-to-back wins.
Dropping into the second tier would be unthinktable for the Gunners, who have won the Premier League three times, have lifted more FA Cups than any other side and have finances that make them one of the biggest clubs in the land.

But their struggles have highlighted just how competitive the top-flight now is and history has shown that no club is too big to go down.
Here are some huge clubs to have dropped down to the second division...
Liverpool
This may have been before their heyday in the 1970s and 1980s but Liverpool's relegation from the old First Division in the 1953/54 season was still a shock.
The Reds were champions in the first league season after the Second World War but found themselves in the second tier seven years later due to a gradual downturn in form.

They drifted in the Second Division for five years before the club poached Bill Shankly from Huddersfield in December 1959.
He soon put things right at Anfield, getting them back into the top flight in 1962 before building Liverpool into a 'bastion of invincibility' as he promised he would, which carried on long after he left his post in 1974.
15
Manchester United
Just like Bill Shankly was so important to Liverpool's success, Sir Matt Busby was crucial towards building Manchester United up.
The Scot won three league titles and an FA Cup before many of their players lost their lives in the Munich air disaster in 1958. However, Busby built them back up into a major force as he helped them win the FA Cup in 1963, two league titles (1965 and 1967) before winning the European Cup in 1968.

He stopped being manager the following year and the Red Devils' decline began shortly after. An 18th-placed finish in 1972/73 was swiftly followed by the departures of Bobby Charlton and Denis Law, while George Best's personal struggles were a constant distraction for the club.
And the following season saw what would have been considered unthinkable back in 1968 happen - Man United were relegated. They bounced back to the top flight straight away but it wasn't until Alex Ferguson came in 1986 that they began to have sustained success again.

Tottenham
If you have a friend who supports Tottenham, one of the first things they'll tell you about their club is the fact they're the first English side to win the league and FA Cup double in the same season - even if that happened long before they were even born.
Spurs were a top side under Bill Nicholson. As well as that magical double-winning campaign in 1960/61, he guided them to FA Cup wins in 1962 and 1967 and League Cup triumphs in 1971 and 1973.
15
They also won the UEFA Cup in 1971/72 and the UEFA Cup Winners' Cup the following season.
Nicholson left the north London club in 1974 and just three years later they went down to the Second Division.
But more success came to Spurs in the 1980s, winning the FA Cup two years running (1981 and 1982) as well as the UEFA Cup in 1984.
15
Chelsea
This may shock younger readers but Chelsea Football Club did exist before 2003. And they've suffered relegation heartache too.
In fact, the Blues were a yo-yo club for much of the 1970s and 80s, going up and down between the top two divisions on a regular basis.
15
Their last visit to the second tier came when they were relegated in the 1987/88 season, having struggled with the financial effects of an ambitious redevelopment of Stamford Bridge which made them sell key players.
They went straight back up to the top flight and enjoyed success in the 1990s and early 2000s before Roman Abramovich bought the club and changed the course of English football history forever.
15
West Ham
Just like Spurs fans will tell you about their double-winning season, West Ham fans will constantly remind you about how their players, and their players alone, won England the World Cup in 1966.
However, they single-handedly relegated themselves from the Premier League in the 2002/03 season despite having very talented players, including Michael Carrick, Joe Cole, Jermain Defoe and Paolo di Canio at their disposal.
15
They came back to the Premier League three years later but went down again in the 2010/11 season.
The Hammers have been in the top flight since 2012 but the prospect of relegation is a constant source of worry for most fans.
15
Leeds
In May 2001, Leeds were back in the big time as they were one win away from reaching the Champions League final. Three years later, they were relegated from the Premier League.
The reasons for clubs experiencing financial difficulties are usually rather complex but Leeds' decline is more or less down to them overspending when they briefly rode the European wave.
15
It was a huge shock for those involved with a club that was at the top of English football for so long under Don Revie.
It took them an arduous 16 years to get back into the big time. Arsenal fans won't want to wait that long if the unthinkable happens.
15
Newcastle
While this decline was not as rapid as Leeds, Newcastle's relegation to the Championship in 2009 hurt fans hugely, especially when you consider how good they were not long before.
We all know how close Kevin Keegan's hugely entertaining side came to winning the Premier League in the 90s but they were a useful outfit under Sir Bobby Robson too.
15
They had exciting spells in the Champions League, albeit not making it as far as Leeds, as well as runs in the UEFA Cup after that.
But things really went downhill after Mike Ashley bought the club in 2007, with all sorts of internal problems manifesting into poor performances on the pitch and relegation two years later.
