Ajax coach Frank de Boer has agreed a new four-year contract with the Eredivisie champions.
Ross County boss Derek Adams has handed nine players new deals on Tuesday.
Hamburg coach Thorsten Fink has described Liverpool's Dutch forward Dirk Kuyt as a "class" player.
Kuyt, 31, has a year to go on his current deal at Anfield but there is speculation he could leave the club in the summer after six years in England.
Fink, who has steered Hamburg to Bundesliga safety after the club endured a dreadful start to the season, is a big admirer of the former Feyenoord man.
He told www.kicker.de: "He has class, and he is also a fighter. There is nothing more that needs to be said about the quality of this player. Whether this is something we feel we want to commit to, we will see."
Fink's comments follow similar sentiments from the club's technical director Frank Arnesen a couple of weeks ago.
"A player like Kuyt, who is still in good shape, can add something to any team," the Dane told Bild. "He is a real team player with an excellent attitude."
