Tommy Bell says an LV= Cup semi-final at Welford Road is a fantastic prospect - but Leicester Tigers first have work to do on the league front.Bell scored his first try in a Tigers shirt in Leicester's 43-9 LV= Cup victory at Cardiff Blues, which helped book their place in the last four of the Anglo-Welsh competition.   Tigers face Cup holders Exeter Chiefs at Welford Road in the last four on Sunday, March 15 (kick-off 1pm) and tickets are now on sale to season ticket holders and members. Season ticket holders and members have priority status to book their places before tickets on general sale from 8.30am on Friday, February 13. But before the semi-final clash, Tigers face four fixtures in the Aviva Premiership, starting with Friday's game against Gloucester Rugby at Welford Road (7.45pm).   And Bell said: "The squad is focused on the Aviva Premiership. We have some tough games coming up but this can act as a boost going into those games.   “The LV= Cup is a brilliant competition. I have never been in a position to play in a semi-final. It will be fantastic back in Leicester, in front of a big crowd, in front of the home fans – there won't be many more opportunities like that.”   Book tickets to Friday’s Aviva Premiership game against Gloucester and the LV= Cup semi-final with Exeter  on 0116 319 8888 (option 2), online by clicking here and in person at the Welford Road ticket office.
