Neil Lennon is ready to splash a chunk of the £25million banked from Kieran Tierney. And the Celtic manager has revealed he may have as many as five more new players in his sights as the champions look to reinvest the riches they have secured by the sale of their prized asset to Arsenal. Tierney has completed his switch to London on a bumper five-year contract. The 22-year-old joined the English Premier League giants after the long-running transfer saga was finally concluded just prior to the close of the transfer window south of the border. Lennon was hopeful that Tierney would stay, but the manager understands the huge opportunity which the Scotland has been handed and is now intent on finding the suitable replacement and adding more quality elsewhere in his squad. Asked whether he’d ask for all the cash, Lennon joked: “Yeah. I’ll be standing with my hands out!” But on a serious note, the Celtic boss then confirmed he wants a strong ending to the market and continued: “We’ll look to bring another left-back in, no question. “A right back as well. And a left winger. And a right winger. And maybe a centre forward.” Lennon hailed the left-back after his deal to North London was confirmed. He said: “This is an opportunity Kieran wanted to take and while we will be sad to see him leave the club, we wish Kieran all the very best for the future. “Although he is still a young guy, Kieran has given the club so much. He’s a great lad and I’ve really enjoyed working with him. I’m sure he will continue to progress and develop and make a big impact in the English Premier League. “It has obviously been a long process, but now it has been finalised we can now look ahead and concentrate on continuing to build our own squad and meet the many challenges ahead, domestically and in Europe."
