5 of the best transfer bargains in the history of modern football

#2 Robert Lewandowski to Bayern Munich

Lewandowski has been a vital cog in Bayern's recent success

In 2013, Polish hitman Robert Lewandowski was at the top of his game. He was easily regarded as one of the most prolific scorers in European football currently and was on the wish-list of a number of clubs.

Dortmund was hoping to make some money off his back but the striker had other ideas.

Some might say they deserved something, considering the lengths former Dortmund manager Jurgen Klopp went to.

The player was scouted over 30 times, with the current Liverpool manager traveling to Poznan in a cap and hood pulled over his head. No stone was left unturned to sign him for a measly £4 million transfer fee.

In November the same year, he signed a pre-contract with Bayern Munich and was to join their direct rivals for free. He was set to sign a new contract, but a dispute over wages meant that the Bosman ruling had the final say once again.

Having watched Mario Gotze leave to a direct rival probably struck him as well, considering that he was a vital part of a talented attacking trio consisting of Marco Reus too.

It was virtually unheard of for someone of his stature and age to move for nothing and he proved his worth.

The striker has been instrumental to their success since he joined, leading the team out with the confidence that the 'big man up-front' will pull a rabbit out of the hat to save them.

Fast-forward to current day, on March 31st, 2018 the Polish talisman scored a sensational hat-trick against Borrusia Dortmund, reminding them of what could have been theirs.

As the record stands, at the age of 29, he has a mammoth 150 goals in 194 games for the Bavarian giants.
