Impatient Haaland will leave Dortmund if they fail to qualify for the Champions League...

A video of Erling Haaland went viral on Saturday afternoon as he furiously stormed down the tunnel after Dortmund's 2-2 draw with Koln, in which he scored a brace as his side dropped more points in the Bundesliga.

As per Sportsmail, The Norwegian striker, who has scored a remarkable 33 goals in 31 games this season, is growing increasingly frustrated that Dortmund look likely to miss out on the Champions League next season. The "Millionaires" are currently four points behind fourth-placed Frankfurt with eight games left to play this season.

Also, according to AS, Haaland is fully aware that he needs to be playing in Europe's top club competition and cope with the possibility that he might not be involved in it next season.

It is claimed by the Spanish outlet that Haaland has even told agent Mino Raiola in no uncertain terms that he will leave if Champions League football is not assured at Dortmund next season.

Haaland only signed for the Bundesliga club back in January 2020 after a stunning breakthrough spell at Red Bull Salzburg but is now wanted by almost all of Europe's top clubs.

It is thought Haaland has a 124.5 million USD (13.6 billion KSH) buy-out clause - which must be paid all at once. It does sound like a mind-blowing sum but that is not an astronomical fee for a player who looks likely to score a record-breaking number of goals in the years ahead.

His progress has been so impressive that Chelsea, Manchester City, Manchester United and Real Madrid are all ready to break their piggy bank for him this summer.

That interest, coupled with Dortmund's financial woes caused by the coronavirus pandemic, means they are likely to sell at the end of the season. Real have reportedly made him a 'priority' signing and see him as the long-term successor to Karim Benzema at the Bernabeu.

It's also claimed Haaland 'likes the option' of playing in Spain and the close bond between Dortmund chief Hans-Joachim Watzke and his colleague from Real Madrid Florentino Pérez could work in their favour.

Pep Guardiola's City are thought to be currently leading the chase, with the Norwegian striker contemplating a move to the side his father, Alf Inge, spent three years at before injury cut short his season.

City are looking for a new forward with club all time top scorer Sergio Aguero expected to leave the Etihad this summer while Chelsea are desperate to sign a centre forward after Timo Werner's struggles to make immediate and powerful impact.

Manchester United are also interested in signing Haaland, a player Ole Gunnar Solskjaer coached at Molde, but the Red Devils look set to be priced out of a move as they look to address other areas of their squad.

Haaland's frustrations were there for all to see on Saturday as he threw his shirt away and stormed down the tunnel after Dortmund's draw at Koln.

He was heard saying swearing about his side's current form and, according to German outlet BILD, Haaland was overheard shouting 'I f****** hate this. F****** bulls***' at the half-time break, with his side drawing 1-1 at the interval.

Since joining Dortmund for 27 million USD (2.9 billion KSH) in January 2020, Haaland has scored 49 goals in 49 matches in all competitions and has solidified his status as one of the top strikers in world football.

The German club do have a history of selling on their key players for a profit, with the likes of Gabonese Pierre-Emerick Aubameyang, French Ousmane Dembele and American Christian Pulisic all moving to giants of European football.
