Two weeks ago Newcastle were first linked with a move for Ruben Semedo.

The Portuguese media said that Rafa Benitez had registered his interest in bringing the 23 year old centre-back to St James Park.

First choice for Sporting Lisbon this season, Ruben Semedo has helped them to third place in the domestic league and he also turned out half a dozen times in the Champions League, playing against the likes of Real Madrid and Borussia Dortmund.

Contracted to Sporting until 2022, the centre-back (can also play defensive midfield) has a 45m euros (approx £39m) buyout clause in his contract.

Apart from the actual size of the buyout clause, there is nothing surprising about it, as it is common practice for players on the continent to have these clauses inserted when committing long-term. Security for the club but also allowing players to move on if a club comes in who they want to relocate to AND who are willing to pay the buyout clause.

Considering he has only started 50 top division matches and has only so far played up to Under 21 level for Portugal, that 45m euros buyout clause is obviously unrealistic considering what he has achieved so far.

However, after only finishing third and 12 points behind champions Benfica, Sunday morning brings reports that Sporting are willing to take far less than that buyout clause amount, in order to help bring in the players who could bridge that gap between them and Benfica (and Porto who finished six points ahead in second).

The big question for Newcastle is exactly what will represent value for money in this transfer market, with increasingly crazy predictions of what players will move for this summer.

Portuguese newspaper O Jogo say that they understand Sporting are willing to sell Ruben Semedo for 20m euros, which is just over £17m.

Other European clubs are also reported to be interested in moving for a player who certainly has potential but does Rafa Benitez see him as a player who could step up to the Premier League?
