After a breakthrough campaign at Porto last season every top club and their dog, from Barcelona to Manchester United, began to be linked with Eliaquim Mangala and Chelsea are the latest outfit reported to be interested in signing the French centre-half.
The Blues are currently fourth in the Premier League and can be backed at 3/1 for the title, having conceded just twice in five games.
Here we run the rule over their latest potential big-money signing from the Portuguese champions.
The 23-year-old is a formidable athlete who stands at a well-built 6ft 2in tall and as such he’s well-equipped to tussle with the more agricultural end of the striking spectrum he might encounter in the Premier League.
His athleticism also includes a generous helping of pace for a centre-half and an excellent leap.
As is to be expected from a man of his prodigious physical gifts he is superb in the air, but on the on the ground he is open to improvement, both in terms of the techniques of defending (blocking and tackling) and the mental side of the game (positioning and discipline).
Luckily his pace usually gets him out of trouble if his positional sense has been lacking.
Much like David Luiz, Mangala loves a sortie forward and gets his head on the end of crosses, managing a highly respectable seven goals in 39 appearances for the Dragons last season.
Check out his backheeled effort against Nacional for the kind of strike you wouldn’t see from John Terry.
2012/13 was the breakout campaign for the Frenchman, who took advantage of Maicon’s injury to nail down his place in the Porto side.
In total that encompassed 23 appearances in the league and eight Champions League run-outs and he also earned his first cap for France during the season.
The Express recently estimated his release clause to be in the region of £38m and with Porto having sold Joao Moutinho and James Rodriguez for megabucks this summer his owners are in no need to sell for less.
