Dogan Alemdar (Rennes)

Alemdar made a move in August from his boyhood club Kayserispor to the Ligue 1 outfit Rennes, where he is currently the second choice keeper behind the Senegalese shot-stopper Alfred Gomis.

Up to now, he’s made six league appearances for Les Rouge et Noir, in which he has kept three clean sheets and conceded a total of five goals.

Very much in the mould of a traditional goalkeeper, Alemdar relies on his physical attributes and work rate to command his area and stop the ball from going into his net. Unfortunately, he is pretty awkward with the ball at his feet, so he won’t contribute to build-up play.

And with a price estimated between 2.5 – 7.6 million pounds, he is an absolute bargain.

Julen Agirrezabala (Athletic Bilbao B)

Agirrezabala is the second-oldest player included in this list, having been born on Boxing Day of 2000. Naturally, that means that he is more developed as a player than anyone we mentioned so far, even though he hasn’t had a lot of first-team football. He’s only made four appearances for the Basques, conceding five goals and keeping just one clean sheet.

His passing and technique are on a reasonable level, but where he lacks is in the physical segment. He has a decent pace, but his 7-rated strength makes him easy to bully when in close-contact situations. That’s not a good sign, especially since physical attributes are notoriously hard to improve by training.

Giorgi Mamardashvili (Valencia)

The 20-year-old Georgian goalie is already moving up in European football, having completed a move from Dinamo Tbilisi to the Spanish giants Valencia this past summer.

Los murcielagos first signed him on a loan deal, but he impressed manager Jose Bordalas so much that they made the deal permanent. He even got twelve starting opportunities, which eventually earned him an international cap for Georgia. He is the oldest player on this entire list.

You are getting a player ready for the first team for a bargain bin price of around 2.7 – 8.2 million pounds and still has a lot of room to improve.

Coniah Boyce-Clarke (Reading)

Another player that is very much on the raw side, the 18-year-old, is already showing a physicality beyond his age, which is always a great bonus since physical attributes usually see the least amount of progress in later years.

But aside from that, the Englishman also shows signs of great technical potential, with agility and touch that is more than decent for a man of his size. Along with the rest of the goalkeeping attributes, that are the foundations on which his development should be based.
