Chelsea will test Tottenham's determination to retain Luka Modric with an improved £30m bid for the Croatian playmaker this week.

Andre Villas-Boas is set to meet Chelsea chief executive Ron Gourlay in the next few days to discuss whether they should increase their £27m offer for Modric. Tottenham have already rejected two bids of £22m and £27m from the Stamford Bridge side.

But Chelsea remain quietly confident £30m should finally land the unsettled midfielder.

"I don't like talking about players from other clubs, but that's something we'll look at during this week," Gourlay said after Chelsea's 2-0 victory over Aston Villa in the final of the Asia Trophy. "We really need to sit down with Andre and talk this through."

Villas-Boas is believed to be keen to add a creative midfielder and a winger to his squad before the start of the new season.

The west London side have already lost out on Javier Pastore - after he joined Paris Saint-Germain in a €40million move - and reports today suggest Chelsea could launch an audacious bid for Real Madrid playmaker Kaka, should they be unsuccessful in their pursuit of Modric.

The Brazilian playmaker found himself surplus to requirements at the Santiago Bernabeu last season after the arrival of Mezut Ozil, and Mourinho will consider offers around £25m for the midfielder, according to the People.

Meanwhile, Chelsea could miss out on Anderlecht striker Romelu Lukaku after the Belgian cooled on speculation linking him with a move to Stamford Bridge.

"I want to go to a club where I can develop further. It's not that I just want to be transferred to Chelsea," he said.

"At the moment I am patient. I remain at Anderlecht and I am not thinking of a transfer."
