It looks increasing likely that Luka Modric will leave Tottenham this summer with the main subject of debate now being which of Europe's top clubs he will join.

Manchester United has been strongly linked to a £30 million move for the midfielder, but it appears that no bid has yet been lodged. Paris Saint-Germain is also thought to be pursuing the Croatia international.

With Tottenham dismissing boss Harry Redknapp on Wednesday, speculation has only increased over Modric's future. The 26-year-old's Spurs and Croatia teammate Vedran Corluka has even chimed in ahead of his country's match with Italy at Euro 2012 on Tuesday.

We all know it will be very difficult for Spurs to keep Luka because they do not have Champions League football next season, he said, according to the Sun.

Luka is one of the best players in the world and the kind who wants to play in the best competition.

Not getting into the Champions League will cost Spurs next season, even though they were unlucky to get fourth place and still not be there.

Even with Modric's desire to leave Spurs chairman Daniel Levy is sure to play hardball over negotiations. Something that can also be said of Borussia Dortmund general manager Hans-Joachim Watzke.

Having already lost Shinji Kagawa to United this summer, the Bundesliga side is determined not to lose another key asset in striker Robert Lewandowski.

I don't know how often we have got to stress that Robert Lewandowski will certainly be staying with us, Watzke said, according to the Mirror.

With respect, Manchester United did come looking for him.

He was given the chance to fulfill a childhood dream. But we are not forced to sell anybody for financial reasons.

One target that United definitely won't be singing this summer is Kwadwo Asamoah. Juventus have confirmed that they have agreed terms with Udinese for the Ghana midfielder, who has been in Turin on Thursday undergoing a medical.

It always appeared likely that Asamoah would stay in Italy, despite reports that Sir Alex Ferguson was maintaining an interest as he looks to reinvigorate his midfield this summer.

United, though, have confirmed their second transfer of the summer with the arrival of highly-rated youngster Nick Powell from Crewe.

The 18-year-old attacking midfielder has arrived for a fee that will eventually reach in excess of £4 million, according to the Manchester Evening News.

And Powell will encounter a familiar face at Old Trafford in the form of youth coach Colin Little, who, as a former coach at Crewe, worked with the England youth international during his formative years. Little spoke of his experiences of Powell's early ability, which should give United fans plenty of encouragement.

I have a smile on my face when I return home after training after seeing what they can do and that's how I felt when I used to see Nick as a 13-year-old. he said, according to the Manchester Evening News.

It sounds mad but some of the things he was doing with a ball was stuff that I used to watch Cristiano Ronaldo doing for United. He had feet like Ronaldo.

A lot of people will only have seen little clips of what Nick can do from the TV but that is nothing to what I have seen him do in training. He was doing stuff I'd not seen others do before.
