We have a 31 year old injury prone striker. He appears to be on a rapid decline and has looked slow and static. We have Rooney who turns 29 in a month and also looks on the decline. Has shown no pace and continually slows down our attacking play. Also these two haven't been able to form a functioning partnership yet we insist on playing them together. Also, arguably a reason why they have looked poor is because we aren't creating enough chances.
Then we add a 28 (going on 29 soonish) Falcao. Coming back off an ACL injury, and hasn't looked like reaching his pre-injury form. He isn't overly quick, he will finish off chances however (but, we don't create chances). We look miles off Chelsea, City, and Liverpool. We don't look like beating Arsenal either. If we don't make top four this season or next then we have three aging players, all on HUGE money, and we sold our best young forward to a direct rival.
