Tottenham are believed to be keeping tabs on Atletico Madrid boss Diego Simeone, according to the Daily Star.
Although chairman Daniel Levy appointed Tim Sherwood on an 18-month contract only a week ago, doubts persist as to whether he will last the distance in the Tottenham hot seat.
And reports suggest Levy has made Atletico boss Simeone his top managerial choice.
Since being appointed as Atletico boss two years ago, Simeone has been a revelation.
The 43-year-old guided them to Europa League success in his first season in charge, before a thumping 4-1 win over Chelsea in the Super Cup a few months later.
Simeone also bought home the Copa Del Ray last season, after his side beat rivals Real Madrid 2-1 in the final.
And this season, Atletico find themselves level on points with Barcelona at the top of La Liga, and qualified for the last 16 in the UEFA Champions League.
The run of success has caught the eye of chairman Daniel Levy, who was understood to have identified Simeone as a top target before appointing Sherwood.
However, the Argentine would be reluctant to leave the club midway through the season, meaning no official approach was made.
That could all change in the summer however, depending on whether Sherwood can guide Tottenham to the Champions League places, with a host of top clubs believed to be preparing an approach for the Atletico boss.
