West Ham have been extremely active in the transfer market so far this summer but the latest reports emerging will leave fans concerned.

TalkSport state the Hammers are willing to listen to offers for Marko Arnautovic following the signings of Felipe Anderson and Andriy Yarmolenko, the former of which is a club-record deal.

Arnautovic signed from Stoke City last season and, following a slow start, excelled for West Ham by scoring 11 Premier League goals to aid the Hammers in their battle to avoid relegation and was crowned Player of the Year in the end of season awards.

However, amidst reported interest from Manchester United and Roma, West Ham are said to be open to offers for the 29-year-old Austria international following their spending spree.

If that was to be the case, then there is a real danger that Manuel Pellegrini could be set to undo the hard work he has done in the market this summer and West Ham must ensure Arnautovic remains in the squad.
