West Ham defender Jose Fonte is full of praise for Tottenham boss Mauricio Pochettino.
The pair worked together at Southampton.
"It helps massively to have a coach who played in the same position as me," Fonte told West Ham's official website.
"In my last few years I've been lucky in that I've had Mauricio Pochettino, Ronald Koeman and now Slaven, so I've had the opportunity to learn from the best and I will improve however I can with him. I just want to get better.
"You take anything you can from your managers, but the small details make the difference. You've got to pay attention because when managers like them speak, they know what they are talking about.
"With Pochettino, for example, we worked a lot on improving the physical aspect on the training ground, on interceptions, on playing out from the back, making the right angles, sliding across to be in the right positions all the time, and the distances between the players in the back four – small details that you pick up along the way."
