Bursaspor's head of youth development Necmettin Kocaman has confirmed Chelsea have tabled a bid for 15-year-old striker Enes Unal. The teenager has caught the eye of clubs across Europe, with his prolific tally of 170 goals in 102 games for Bursaspor's academy.

The Daily Mail reports the Blues have made a bid in the range of £1.75m for the player and are hopeful of landing the striker, amid interest from Manchester United and Manchester City. Unal is set to represent Turkey in the U20 World Cup this summer and Chelsea are looking to make a quick swoop, in anticipation of growing interest in him after the tournament.

"Chelsea have made an offer for Enes, however, we hope he will play for our senior team before making such a move," Kocaman said.

Clubs across Europe are bringing in young talents as they prepare themselves for the Financial Fair Play rules that are set to come into effect in 2014. Cash-rich clubs like Chelsea and Manchester City are investing more in youth, so as to create potential first-teamers from their academy and not depend on having to pay exorbitant fees for the procurement of world-class players.

David Luiz Focused on Russia Game

Meanwhile, Chelsea defender David Luiz believes Brazil have to play a perfect game if they are to beat Russia in the international friendly at the Stamford Bridge on Monday. Brazil have already qualified for the 2014 World Cup as the host nation, while Russia have had their qualifier against Northern Ireland postponed.

"I expect it will be a very difficult game, because they are a strong team and they are rested. They have great players, and I believe Brazil has to play almost a perfect game to win. It's always special to play for the national team and wear the shirt, and tomorrow will be another special day - to play for my national team in my home stadium. But I don't want to take my focus off the game tomorrow, so that's what I'm thinking about," Luiz said.
