After failing to gain promotion, the club were under financial pressure and were forced by their bankers to raise cash,[2] which led to Rasiak being sold to Premier League side Tottenham Hotspur for a fee said to be up to £3 million.

On his arrival, manager Martin Jol described Rasiak as "a tall target man, a hard-working, honest player with a good goal scoring record.

After mid-January he lost his place in the starting eleven to fellow countryman Marek Saganowski, but finished the season as the club's top goalscorer with 21 goals.

On 31 January 2008, Rasiak secured a loan move to Bolton Wanderers until the end of the season after Gary Megson decided to bolster his attacking options after the departure of Nicolas Anelka to Chelsea.

[8][9] Following his loan move Rasiak admitted it was not an easy decision to join Bolton Wanderers, but that he intended to be part of the Poland squad for UEFA Euro 2008.

[10] On 9 February 2008, Rasiak made his first appearance for Bolton when he came on as a substitute for El Hadji Diouf in a defeat to Portsmouth at the Reebok Stadium.

On 15 August 2008 Rasiak signed on loan with fellow Championship side Watford until the end of the 2008–09 season, with the option of a permanent transfer.

In January 2009, Rasiak scored in FA Cup matches against Scunthorpe United and Crystal Palace to help set up an unexpected fifth round tie against Chelsea.

He was ruled out for a month after picking up an injury against Nottingham Forest in March[13] which was a blow to Watford as Raziak appeared to be forging an unbeatable partnership with Priskin.

Both strikers got on the scoresheet in both of Watford's wins against Charlton Athletic and Nottingham Forest[14] (the same match in which Rasiak got injured) that took place within three days of each other in March 2009.

[28] Rasiak made his international debut for Poland on 10 February 2002 in a friendly match with Faroe Islands under manager Jerzy Engel.
