West Ham United boss Sam Allardyce is well aware of interest arriving for Aaron Cresswell.
Allardyce wrote in the London Evening Standard: "This is the time of the season when speculation about players' futures begins to increase.
"For example, Aaron Cresswell has been linked with several clubs including Chelsea and Manchester City this week.
"Aaron has had a good first season in the Premier League. He's played every game and has shown a good level of consistency. He knows he can improve further and I am sure there is absolutely no desire at West Ham to let him go.
"What makes players like him attractive to the big clubs is that he is home-grown and squads must have eight of those in the Premier League and five in the Champions League."
