Arsenal need goals, Man United need a forward: What top Premier League clubs still need

Manchester City , Arsenal and Liverpool underlined their status as favourites to challenge for the title with opening weekend wins.

Manchester United made a winning start after last season's eighth -place finish, but Chelsea lost their first game under new coach Enzo Maresca .

With less than two week to go before the window closes, what are the top priorities before the biggest clubs in the days ahead ?.

Chelsea have 41 first -team players in their squad, says Janusz Michallik .

Enzo Maresca has to focus on drastically reducing the size of the squad and moving several players out.

Manchester United have made four major signings so far this summer , including Joshua Zirkzee from Bologna .

Chelsea are in a catch-22 largely of their own making, with the likes of Raheem Sterling and Ben Chilwell likely to leave.

Paris Saint-Germain's Manuel Ugarte is a long-term target for Manchester United .

United need a proven goal scorer to turn defeats into draws and draws into defeats.

A proven goalscorer would transform United and have the ability to rescue seemingly lost causes.
