Reading on Bolton's fans Forum people seem to suggest he struggles to play in a 1 man attack and needs support from another. Again 1 goal in 5 games there as well. Seems like he is a hard worker and put's in a shift. Sounds like the sort of player some will love others will hate.
Overall though his stats are not prolific. 1 goal in 5 games is his ratio currently from his time with Plymouth, Cardiff and the loan spell at Bolton this year.
