Villa have got Jota, El Gazi, Trezeguet and Green and arguably Kodja all vying for places out wide. I also expect to see Grealish pushed further forward this season with all of the acquisitions made in midfield so don't see there being much truth in this.
Re Phillips, as ever, I am happy to let any player go as long as they are adequately replaced. At his age, with his injury record allied to the fact that pacy wingers regress quicker than other positions as well as his contract situation, I wouldn't mind cashing in. That said, we are lacking a starting winger currently, selling Phillips means we would require 2 and there isn't long left in the window.
