Mauricio Pochettino believes he cops unwarranted flak when Tottenham signings do not work out.

While many players brought in by Spurs in recent years have proven a success, their ineffective acquisitions have been brought into sharp focus after Vincent Janssen finally made a permanent exit.

The Holland striker will look to rebuild his career at Mexican side Monterrey and Pochettino was at pains to stress that Spurs' failures should not be viewed as his fault, just as he does not feel he deserves credit for successes like Son Heung-min.

"It doesn't surprise me but it's good to see how the people love him and how important he is for the people.

"I am happy to hear him telling you that he still wants to improve, be better and work hard.

"That mentality is fantastic and that is why he is a very good example for all the fans and all the people, not only here but in Asia if not the word."
