Quick decisions are rare in this game, especially when such big sums of money are changing hands. There is no doubt a lot of posturing as well as the obligatory to's and fro's.
Greg Van Der Weil was linked with a move early last week. No more news on that one, but he would be a great addition.
Song has spent a lot time in the last two seasons venturing forward. Whilst this has paid dividends for RVP (see some of the best through balls ever) it has left the defense exposed to the counter attack.
Sahin is an attacking midfielder, so a different kettle of fish to Song. M'Vila may be considered a direct replacement though, although he is thought to be a loose cannon.
I'm not sure how it will pan out, but if we get an offer for £15m for Song, sell and get M'Vila. Sahin should not be considered a replacement for Song, but to cover for the injuries of others as he can play on either wing, or in the middle.
Who would rate him more highly than Diaby, Gervinho, Walcott or Rosicky?
