Having worked with the former Rangers boss in the past on more than once occasion, Lens is certainly not a stranger to Advocaat, and the hope for both individuals, and of course the Sunderland fans, is that the 27-year-old will quickly adapt to the Stadium of Light under his compatriot's management.
“It’s my third time working with Dick Advocaat, and I’ve had good periods with him," Lens is quoted as saying in the Chronicle. "At PSV I reached by own personal goalscoring record, 15 in one season. So I hope I will do the same now, or score even more.
“He’s a good manager who tries to get the best out of his players."
The player actually scored 19 times in Advocaat's season at PSV from 2012-13, with 15 alone in the league. It was at Lens' first club AZ where he first worked with the Sunderland boss, who brought him through and encouraged his early promising form. The forward scored 16 goals in that season, with 12 in the league. Clearly, Advocaat brings the best out in the player, with those two seasons the most prolific of Lens' career.
Lens arrived from Dynamo Kyiv for £8 million according to BBC Sport, having spent two years in the Ukraine. As a versatile attacking player, goals have always been something that Lens is capable of offering, as his 8 international strikes in 30 games for the Netherlands prove. The ex PSV man said he would be looking to make the best use of the time before the start of the season to settle in at Sunderland, labelling the move "a dream" for him.
“I have two or three weeks before the season starts and I will try to adapt as fast as possible," he added.
“For me, this is the start of a great dream, so I’m looking forward to it.”
