Manchester City would be interested in signing Raheem Sterling if he were to become available, according to Sky sources.
Tottenham have completed a deal for Cologne defender Kevin Wimmer and he will join them in June, Sky sources understand.
Vincent Kompany has described Arsenal striker Robin van Persie as a "great player" and believes he would improve Manchester City, or any other squad.
Roberto Mancini's side have been heavily linked with a move for the 29-year-old although reports on Tuesday suggest Manchester United are in pole position to sign the Dutch striker.
"It's very easy to say you want to play next to Robin van Persie," Kompany told Sky Sports News.
"He's a great player. He's proved it so many times last season and any team he would play for he'd make it stronger."
The Dutchman, whose contract expires at the end of the 2012-13 season, announced earlier this summer that he would not renew his deal and was booed by some Arsenal fans during their friendly against Cologne on Sunday.
Team-mate Thomas Vermaelen does not believe the speculation or reception from the Gunners' supporters have had a negative effect on the striker, who scored 37 goals last season.
"To me he looks fit and sharp in training," said Vermaelen.
"He's working hard. He's working on his fitness. I don't see anything (different) and I hope he stays the next four years as well.
"I don't know what happens behind the scenes but at the moment I can only say he's a player for Arsenal.
"I feel really positive for the new season. If we all stay fit, the squad is strong enough to compete for the title."
