Turkish giants Fenerbahce and Galatasaray are keen on making summer offers for Arsenal youngster Joel Campbell, who is currently on a season-long loan at Olympiacos. The Costa Rican starlet has had an impressive season with the Greek champions, making a name for himself with his superb performances in the Champions League. Campbell scored against Manchester United in his side’s 2-0 win in the first-leg of the Champions League last-16 tie. Ever since that performance in Piraeus, the youngster has been tipped for a return to the Arsenal first team for the forthcoming season. However, Arsene Wenger has given no clarification as to whether he wants Campbell to be back in the squad and, as a result, Galatasaray and Fenerbahce are monitoring the situation closely. Olympiacos are also keen on signing Campbell on a long-term deal but the financial muscle of the two Turkish clubs could prove decisive if a bidding war was to commence.
