He isn't, he is 5'10", it even says this in the bit that you quoted. TransferMarket actually has him at 1.82m, which is actually 5'11". According to TM, Bree is 4cm taller than Jelert, but other sources say both are the same.
I find it hard to imagine that Bree will come back enthused to play for us again, having had a very successful time at Charlton and being out of contract in the Summer.
