Liverpool have tabled a formal bid for Barcelona defender Thomas Vermaelen.

Sport says the Reds have now made their interest concrete with an offer for the Belgian.

The English club won't pay more than €10 million for the centre-back, who cost the club €19 million from Arsenal.

However, he has hardly played since arriving almost two years ago.

For the moment, Barça hope there will be more bids from the Premier League, with West Ham the most likely.
