Kyle Walker issued a stark warning to Chelsea`s on-loan player, Joao Felix, during AC Milan`s recent loss.
The defender joined the Italian club on loan from Manchester City in January.

Despite an initial positive period, AC Milan`s performance has declined, and Walker`s frustration seemed to surface.
During halftime, with Milan trailing Napoli 2-0, Walker had some strong words directed at Felix.
As they walked towards the dressing room, Walker called out to the Chelsea player to stop him.
Walker was then heard saying: "Pass the ball, we are not Messi."
Milan managed to score a goal back through Luka Jovic in the 84th minute, but it wasn`t enough to change the outcome.
They are currently struggling in ninth place in Serie A, trailing the Champions League qualification spots by nine points.
Walker, 34, had an undefeated streak in his first four games for Milan but was substituted at halftime in the match against Hellas Verona.
He then sustained a hamstring injury, and Milan lost both games played while he was sidelined.
This negative trend continued against Lazio when Walker returned from the bench, although they subsequently achieved victories against Lecce and Como.
Away from the field, the right-back recently signed a contract to model underwear for Hugo Boss.
