Everton have made an offer for Rennes winger Kamil Grosicki, according to reports.

French website Le Telegramme claim that a substantial undisclosed bid has been tabled for the 28-year-old.

HITC Sport citing the French publication report that new Everton manager Ronald Koeman repeatedly watched the Poland international while at Southampton and is keen on bringing him to Goodison Park.

Grosicki has scored eight goals in 42 international appearances and notched nine goals and four assists this season for Rennes.

Gerard Deulofeu, Aaron Lennon and Steven Pienaar are likely to slip down the pecking order in the battle for the flank roles if Everton are successful in signing Grosicki.

The Rennes number 10 is contracted to the club until 2020 so Koeman may have to be prepared to pay a premium for his services.

Grosicki has played for six different teams since completing his youth career with Polish outfit Pogoń Szczecin but is currently focusing on his national team as he competes for Poland at this summer’s European Championships.

The striker is yet to score in the tournament and did not take a spot-kick as Poland beat Northern Ireland 5-4 on penalties on Saturday evening.

The forward has won the Polish Cup in 2008 and 2010 with Legia Warsaw and Jagiellonia Białystok respectively.
