Charlie Nicholas’ forecast
West Ham had a wonderful result last week and I am happy for David Moyes. There has been a slow advancement for Arsenal under Mikel Arteta and I enjoy his authority.

I am excited about the development of the kids, and for the first time in a while, I believe there is real hope for those coming through. Bukayo Saka, Reiss Nelson, Joe Willock, Gabriel Martinelli and Eddie Nketiah have really powerful Arsenal futures.

West Ham will be a few and Michail Antonio seems the ideal solution for them at present with his pace and power, but I still feel there is a vulnerability about their defence. I believe it’s going to be a hectic day for Lukasz Fabianski back in his old club.
