Indeed, Dicks, who has been appointed to Slaven Bilic's backroom staff, was full of praise for the Frenchman when asked how he is looking in training on Twitter.
Payet arrived at Upton Park for a £10.7 million fee this summer, as quoted by the Daily Mail.

Meanwhile, Dicks also gave his verdict on Stewart Downing's West Ham departure when asked by a follower.
The winger has left West Ham for Middlesbrough, with the deal being confirmed on Thursday night, and Dicks feels the 30-year-old will be a loss due to his ability and work-rate.
When a player wants to go, however, the Hammers coach feels there is little you can do.
He was a good player and worked hard in training, but when a player wants to go, what can you do. https://t.co/zKPqjBRlV7— Julian Dicks (@JULIAN3DICKS) July 17, 2015
As much as Downing's form had tailed halfway through last season, he was still West Ham's most creative player - and one of the Premier League's - but Payet's creativity in Ligue 1 has been well documented. For a fee as high as £10.7m, Hammers fans will no doubt hope the Frenchman can more than compensate for Downing's departure.
