 During Wark 's time at Drumchapel , he attracted the attention of Celtic . He trained with the club at their Parkhead ground , before receiving an invitation to sign schoolboy forms for the club . As a lifelong Rangers fan ( with whom Celtic have a notable rivalry ) and with interest from " several English clubs " , including Bristol City , Manchester City and Ipswich Town , Wark stalled on the offer . He trialled with both Ipswich Town and Manchester City , and selected Ipswich when the latter remained non @-@ committal . On arrival at Portman Road , Town manager Bobby Robson , later described by Wark as the person in football " who had the single biggest influence on [ him ] " , personally welcomed him and Wark signed with the club as an apprentice .
