Steven Fletcher would become the joint fourth most expensive striker in Europe

Fletcher himself has handed in a transfer request in an effort to force a move to the Premier League club, Tweeting that his 'head was gone.'

Many are calling Wolves' valuation of the player they paid £7.5 million for two seasons back unrealistic. Fletcher scored 12 times in 26 games last season.

A look at the summer's transfer deals around Europe show that at £15 million the striker would become the joint fourth most costly in Europe.

Here's a look at the four who would exceed his valuation.

Ezequiel Lavezzi - Napoli to PSG, £23 million

Zlatan Ibrahimovic - AC Milan to PSG, £18.5 million

Lacina Traore - Kuban Krasnodar to Anzhi, £16 million

And joining him on £15 million - 

Marco Reus - Borussia Moenchengladbach to Borussia Dortmund £15 million

So there's a thought. for just £3.5 million extra than the fee Wolves are demanding, Sunderland could have snapped up Zlatan Ibrahimovic. Mind boggling.

What about those whose transfers he exceeds? Here are the rest of Europe's top 10 biggest fees laid out on strikers this summer.

Fabio Borini - Roma to Liverpool, £11.5 million

Mario Mandzukic - Wolfsburg to Bayern Munich, £11.5 million

Lukas Podolski - Koln to Arsenal, £10.5 million

Luuk de Jong - Twente to Moenchengladbach, £10.5 million

Olivier Giroud - Montpellier to Arsenal, £10.5 million

Paulo Dybala - Instituto to Palermo, £10.5 million

Not bad company for Steven Fletcher to find himself in, not that he will be taking any solace in the situation. There is no doubt he is important to Wolves, but it seems to us their valuation is a little unrealistic. £12 million was more than fair, and by continuing to dig their heels in they are doing nobody any favours, including the player himself.

What do you think, is Fletcher overpriced? Should Sunderland pay the £15 million?
